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.

An electromagnet starts with a battery (or some other source of power) and a wire. What a battery produces is electrons. ... A small magnetic field is generated in the wire. It is this small magnetic field that is the basis of an electromagnet. ... Experiments to Try!

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).
