It is fairly easy to build an electromagnet. All you need to do ... A thicker core might make a more powerful magnet. Just make certain that the material you choose can be magnetized. You can test your core with a permanent magnet. If a permanent magnet is not attracted to your core, it will not make a good electromagnet.

There are a few equations to have handy: 1. The force generated by an electromagnet is approximately: F = mu_r^2 * mu_o * N^2 * I^2 * A / (2 * L^2), where mu_r is relative magnetic permeability of the magnet core.

4. Now you have an ELECTROMAGNET! Put the point of the nail near a few paper clips and it should pick them up! ... NOTE: Making an electromagnet uses up the battery somewhat quickly which is why the battery may get warm, so disconnect the wires when you are done exploring.

This creates a powerful magnetic effect inside the coil called an electromagnet. The magnetic field inside the coil causes the tiny magnetic fields in the metal of the nail to be aligned in one direction (all the north poles point the same way).
