Build an electromagnet in 5 minutes

Build an electromagnet in 5 minutes

Here’s something a bit easier than the motor from the last email.

A simple way to build your own electromagnet!

…which is pretty cool:

1. Take some insulated wire.

2. Wind it around a screw, maybe about 50 times.

3. Connect a big 1.5 V flash-light battery

Place it over some small metallic objects to test it.

Note: Not all metals are magnetic. For example copper coins won’t be attracted to the magnet.

Keep on Soldering!
