You'll need

some magnet wire

a nail

a battery

a compass

some staples, paperclips and other things with iron in them

 

Do It!

Wrap the magnet wire around the nail, keeping both ends of the wire out of the wrap.

Strip the insulation off of the end of the wire with sandpaper, a knife or a file. Nail polish remover can also work.

Connect the wire to the battery.

Use the compass to see the magnetic field change when you turn it on/off and when you switch the direction of the current.

Pick up some small items with your new magnet.

Add a switch to it so you can turn it on and off.

Install your electromagnet on a crane and pick up some toy cars and other junk.
