how to make an electromagnet lesson
Lesson Summary. An electromagnet is created by generating an electric current in a wire. You can create a simple electromagnet just by connecting an insulated wire to a battery. When the circuit is completed, current will flow in the wire, creating a magnetic field around the wire.
Even though electromagnets are used in all kinds of complex technology, they are pretty easy to make. In fact, you can make one yourself using some common household supplies that you may already have! How to Make an Electromagnet. To make an electromagnet, you just need two things: a battery and some wire. Connect both ends of the wire to the battery and you will create a magnetic field just like Oersted did. You can verify that you have made an electromagnet by using a magnetic compass needle, or by placing some iron filings around the wire.
