Two batteries and copper wire. Battery motor. Mobile hand warmer

How to get the most out of a battery? How to make fire without matches and a lighter? How to "bury" the battery correctly? It is difficult for a civilized person to imagine life without batteries. But, as experience shows, we are not sufficiently informed about the possibilities of things that surround our life. 10 life hacks with batteries are proof of this.

1. Mobile hand warmer

• People are divided into two types. Some even feel comfortable in the cold. Others freeze in mid-July. If the problem of cold hands is familiar to you firsthand, keep on hand, or rather in your hands, a mini battery heater. Wrap the battery with foil, securing it to the contact poles. Clamp the poles and enjoy the warmth. Before taking the mini heaters with you, make sure that the batteries are charged.

2. Charged or dead - how to find out?

• But how do you know if the battery is charged without devices? Drop the battery on the table with the minus side from a small height (2-3 cm). Discharged loudly rebound and fall. A charged one will most likely land on the pole with a thud.

3. Do-it-yourself electromagnet

• With the help of simple items - a battery, insulated copper wire (at least 1.5 meters) and a large nail / bolt, you can make a powerful electromagnet. Wind the wire around the nail from one end to the other. Each end of the nail should have "tails" to connect to the battery. As soon as you attach the ends of the wire to the battery, the design will turn into an electromagnet. Look for or pick up any metal objects with them. After disconnecting the elements, the electromagnet loses its power.

4 Battery Fire: Prison Lighter

• One of the favorite tricks of life hackers (and not only) is making fire with a battery. You will need a strip of foil with a paper base (for example, from chewing gum) 6-7 mm wide at the ends with a narrowing of up to 2 mm in the center. Attach the ends of the strip to the poles of the battery and bring the device to the paper, which will immediately ignite.

5. AAA instead of AA

• Need AA, but only AAA is at hand? The problem is solved simply - with a piece of foil that will hold the battery in the slot and bring the device into working condition.

6. Opening the Krona battery

• Alkaline batteries "Krona" contain 6 AAAA batteries with a voltage of 1.5 V, which are easily converted into AAA batteries using the above life hack.

7. Why wrinkle dead batteries?

• A penny saves a ruble. Do not throw away exhausted batteries. If a discharged battery is crushed, for example, with teeth or pliers, it will gain momentum for a second life. By the way, a heavily crumpled battery can leak and ruin the device.

8. Smartphone stylus

• Incidentally, the negative side of a AA battery can be a stylus for a capacitive touch screen.

9. A gift to future generations

• A battery thrown into the trash will cause serious damage to nature. Once on the street, it will pollute 20 square meters of land or 400 liters of water with harmful components. Put used batteries in a plastic bottle, and while it is filling up, find the nearest collection point for batteries, which, alas, are few in Russia.

10. Responsibility to nature with Ikea

The Ikea chain of stores has resumed accepting used batteries and mercury-containing lamps. The store does not charge any fees for the collection and subsequent disposal of batteries. Look for special containers at the exit of the store!

And today we will talk about how to make a fully working model of an electric motor from a battery, copper wire and a magnet. Such a layout can be used as a craft on the table of a home electrician, as a good example for explaining the principles of operation of such mechanisms, and simply as a fun trinket that you can give to a loved one. To make it is quite simple and everyone can do it, you can put it together with your child, which will be great fun. Next, we will provide detailed instructions with photo and video examples so that the assembly of the simplest motor is understandable and affordable!

Step 1 - Prepare materials

To make the simplest magnetic motor with your own hands, you will need the following materials at hand:

Having prepared all the necessary materials, you can proceed to the assembly of the simplest electric motor that runs on just one battery. Making a small electric motor at home is not difficult, as you will see now!

Step 2 - Putting together a homemade

So, in order for the instruction to be understandable for you, it is better to consider it step by step with pictures that will help you visually understand the assembly principle.

We immediately draw your attention to the fact that you can remake and improve the design of a home-made small engine in your own way. For example, below we will provide you with a few video tutorials that may help you make your own version of the engine from a battery, copper wire and a magnet.

What to do if homemade does not work

If suddenly you have assembled a perpetual electric motor with your own hands, but it does not rotate, do not rush to get upset. The most common reason for the lack of rotation of the motor is too much distance between the magnet and the coil. In this case, you only need to trim the legs a little, on which the rotating part rests.

Also check whether you have cleaned the ends of the coil well and whether contact is ensured in this place. The symmetry of the coil also plays an important role, so try to do everything carefully and slowly.

That's the whole technology of assembling a home-made magnetic electric motor at home. If you watched the video tutorials, you probably made sure that you can make an engine out of a battery, copper wire and a magnet with your own hands in different ways. We hope that the instruction was interesting and useful for you!

It will be useful to know:

People have been puzzled by the creation of a perpetual motion machine for a long time. In theory, the possibility of implementing this device is denied by the postulates of thermodynamics. And we won't even try. This is so, for intrigue.

Let's take an ordinary finger battery, neodymium magnet and copper wire. In addition to the aesthetic side, the wire must be bent so that it has a fastening and a center of gravity at one point. This is important for the stability and rotation of the structure.

We assemble the electric motor

We put a battery on the magnet and then we put a wire heart on them. The system starts spinning.

This happens because an electric charge arises in the wire. And this is nothing but the ordered movement of charged particles. Each of them is affected by a magnetic field that deflects the direction of their movement. This deflection is called the Lorentz force. In physical terms, this is the force with which an electromagnetic or magnetic field acts on a point charged particle. A special case of the Lorentz force is the situation when the magnetic field is directed perpendicular to the velocity vector. In this case, the force becomes centripetal.

That is, charged particles move in a circle, creating a rotation of the structure. The particularly curious can even calculate the rotational speed by deriving its formula from the following expression:

The battery will run out after a while, and the movement will stop. But the impression will remain. Memories do not live in a copper heart, unlike the present. Hmm ... Impressions, memories, love, no matter how trite it may seem - why not a perpetual motion machine?!

For the experiment you will need

Stages of the experiment

1. We bend a heart-shaped figure from copper wire, the ends of the wire should not connect.
2. With the help of pliers, we make a small dent on the positive contact of the battery.
3. We put the battery with a minus on the magnet, put the "heart" on top of the battery. The free ends of the wire should lightly touch the magnet.

It is always interesting to observe changing phenomena, especially if you yourself participate in the creation of these phenomena. Now we will assemble the simplest (but really working) electric motor, consisting of a power source, a magnet and a small coil of wire, which we ourselves will make.

There is a secret that will make this set of items become an electric motor. A secret that is both clever and amazingly simple. Here's what we need:

1.5V battery or accumulator.

Holder with contacts for the battery.

• 1 meter of wire with enamel insulation (diameter 0.8-1 mm).

  0.3 meters of bare wire (diameter 0.8-1 mm).

We'll start by winding the coil, the part of the motor that will spin. To make the coil sufficiently even and round, we wind it on a suitable cylindrical frame, for example, on an AA battery.

Leaving 5 cm of wire free at each end, we wind 15-20 turns on a cylindrical frame.

Don't try to wind the spool too tightly and evenly, a small degree of freedom will help the spool retain its shape better.

Now carefully remove the coil from the frame, trying to maintain the resulting shape.

Then wrap the free ends of the wire several times around the coils to keep the shape, making sure that the new binding coils are exactly opposite each other.

The coil should look like this:

Now it's time for the secret, the feature that will make the motor work. It's a secret because it's a subtle and non-obvious trick, and it's very hard to detect when the motor is running. Even people who know a lot about the operation of engines may be surprised by the ability of the motor to work until they discover this subtlety.

Holding the spool upright, place one of the free ends of the spool on the edge of a table. With a sharp knife, remove the top half of the insulation, leaving the bottom half in the enamel insulation.

Do the same with the other end of the coil, making sure that the bare ends of the wire are pointing up at the two free ends of the coil.

What is the meaning of this approach? The coil will lie on two holders made of bare wire. These holders will be attached to different ends of the battery so that current can flow from one holder through the coil to the other holder. But this will only happen when the bare halves of the wire are lowered down, touching the holders.

Now you need to make support for the coil. They are simply coils of wire that support the coil and allow it to spin. They are made of bare wire, since in addition to supporting the coil, they must deliver an electric current to it.

Simply wrap each piece of bare wire around a small nail and you've got the right part for our engine.

The foundation of our first the electric motor will be the battery holder. This will be a suitable base, because with the battery installed, it will be heavy enough to the motor did not shake.

Assemble the five pieces together as shown in the picture (without the magnet at first). Place a magnet on top of the battery and gently push the coil...

If done correctly, THE COIL WILL START SPINING FAST! We hope that you, as in our experiment, will work the first time.

If, nevertheless, the motor does not work, carefully check all electrical connections. Does the coil rotate freely? Is the magnet close enough (if not, install additional magnets or cut wire holders)?

When the motor starts, the only thing you need to pay attention to is that the battery does not overheat, since the current is large enough. Just remove the coil and the circuit will be broken.

What do you do when the electricity goes out at night? Most likely, you light candles and spend the evening waiting for the power to come on. And you can make good use of this time. For example, to light up a room with an ordinary magnet and wire, which will allow the lamp to work without electricity. Or make a motor that can work autonomously.

DIY electromagnetic motor

This homemade electric motor is easy to make from improvised materials at home. It should be noted that such a device can be used not only as a good example, but also for its intended purpose, for example, by attaching a fan to the rotor.

For manufacturing you will need:

• Spoke;
• Thin metal plates;
• Bolts with nuts;
• Copper wire;
• Piece of plywood.

From a metal sheet 0.2 mm thick, cut out 5 rectangular plates 40 by 15 mm. We make holes in the center of all plates and put them on the prepared knitting needle. Next, you need to fix the plates together with electrical tape.

For better rotation of the rotor, the ends of the spokes are sharpened, thereby ensuring the least contact with the surface.

Then, on the axis, it is necessary to fix a home-made current breaker, which is made of the metal from which the plates are made. The dimensions of the interrupter are 3 by 1 cm. This plate is folded in half and put on the axis.

Next, we make the base of plywood. To do this, on a piece of plywood measuring 50 by 50 mm, we drill three holes (two for bolts along the edges and one in the center for installing the rotor). We make a U-shaped holder for the upper part of the rotor from a metal plate. And we drill a hole in the center.

After that, for the manufacture of the stator, we cut out three plates from metal that will connect the bolts in the lower part of the structure and make two holes for the bolts in them. We put these plates on the bolts, and insert the bots into the holes on the wooden platform.

Further, the bolts are wrapped with electrical tape, and 500 turns of copper wire are wound around it. At one of the corners of the wooden structure, a holder for a contact breaker is attached. Electricity is connected to the coils with a voltage of 12 volts.

How to make a motor out of a battery

This electric motor is more of a demonstration character. In order to make the simplest motor, it will take a certain amount of time and improvised materials.

Main elements:

• Battery 1.5 V;
• Small magnet;
• pins;
• Scotch;
• Plasticine.

First of all, it is necessary to make a coil, which will act as a rotor. To do this, we wind enameled copper wire around the battery (6 turns). We thread the ends of the wire into the resulting coil and fix it with knots.

To stiffen the structure, it is better to use a wire with a cross section of at least 0.5 mm.

We bite off the ends of the coil with pliers (they should turn out to be about 4 cm each). We clean one end of the varnish completely, and the second only on one side (it will act as an interrupter).

Next, using adhesive tape, attach the pins to the contacts of the battery. To do this, you just need to attach pins and wrap the battery with tape. Then, a magnet is installed on the battery using plasticine.

We insert the coil into the ears of the pins. In this coil, a magnetic field is formed, due to which the rotation of the movable structural element occurs. If rotation does not occur, swap the coil contacts.

Magnet from the speaker, copper wire and a lamp for making a lamp

The easiest way to bring a fluorescent lamp into working condition is to place it in the electromagnetic field of an ordinary magnet, which is used to work in old Soviet speakers.

The device consists of:

• Round magnet;
• Copper wire.

To make this device, you first need to remove the magnet from the speaker. Further, using a hammer, without applying great force, beat off the metal plates from the magnet with light blows.

Note! If the plates do not move away from the magnet, you can soak it for a while in a solvent.

After the plates are removed from the magnet, it must be cleaned of contaminants. To do this, use a regular rag or rag.

Next, the winding is manufactured. To do this, take a piece of copper wire in insulation. The length of the wire should be long enough to fold it in half and wind the magnet with five turns. The double end of the wire is threaded into the resulting wire eye.

After the magnet is wrapped, an ordinary fluorescent lamp is inserted into the central part of the magnet. This design can be equipped with decorative materials and used as a stand-alone lamp.

The best homemade magnets

The use of magnets in everyday life is so wide that it would take a long time to list them all. But since many are rather entertaining, let's take a closer look at listing the widely used ones.

Magnets are used:

• During installation work;
• Washing windows;
• as holders.

First of all, it is worth noting that the search for magnets is not a very difficult task. Small magnets, you can find in old headphones. More powerful neodymium magnets can be removed from old computer hard drives.

Let's assume that you are working with a wooden structure. In one hand you hold a hammer, and in the other an element of this design. In this case, holding an armful of nails is not very convenient. To do this, you just need to place a magnet in your breast pocket and glue nails to it.

There are situations when you have to tighten screws in hard-to-reach places in which it is not possible to hold the screw. To do this, simply attach the magnet to the metal part of the screwdriver. A magnetized screwdriver allows you to hold a bolt or self-tapping screw on its own.

If you stick small magnets to the computer table (in any convenient place), you can use them as holders for various USB or other types of wires. To do this, small springs are put on the wires (springs from handles can be used), which are a metal magnetized structure.

The force of attraction of a magnet depends not only on its size, but also on the time of its operation.

As an integral element of decor, magnets can be used as fasteners for a puzzle located on the refrigerator door. For this, any photograph is taken, which is drawn on certain elements. A small magnet is glued to each element using ordinary glue. The photo is divided into constituent elements. After that, it is assembled on the refrigerator door in the form of a puzzle.
