Electromagnet is a rather simple device,which can be used for entertainment as well as for building all kinds of electrical circuits. In this article, we'll talk about how to make an electromagnet with your own hands at home. To do this, we do not need any special knowledge of physics or complex components.
What we need
In order to create an electric magnet, weYou will need: an iron nail, a coil of copper wire, a power unit or a battery, a switch, scissors and a soldering iron. Just note that you should not take too thick wire, it is better to choose products with an average diameter. As for the size of the nail, there is no fundamental difference, it all depends on your ultimate goals. Moreover, if you do not have a nail, you can find something similar. For example, some kind of metal rod. We draw your attention also to the fact that the main thing in a rod or nail is its shape. Curved products will not work for us.
How to make a powerful electromagnet: instruction
At the first stage it is necessary to take our nail andgently wrap the wire around it. It is important that each coil densely and evenly adjacent to each other. We make about 3-4 layers of wire. Be as accurate as possible, since if you break the wire, you will have to start everything from the beginning. The next step is to pull out the two ends of the wound wire and connect them to the power supply. If desired, you can add a switch to the circuit, this will simplify the work with the magnet. Then carefully solder all. Now your electromagnet is ready!
Principle of operation
An electric magnet works on a very simpleprinciple. When applying current to the coil, it is magnetized and begins to "magnetize" the metal elements. The power of the product you make is directly proportional to the number of turns and layers of copper. Thus, the more you screw the copper, the more powerful your magnet will be.
