Magnets are one of the most fun things to experiment with. With a few materials you can easily make your own electromagnet.

Step 1: Materials
- Insulated Copper wire - thin insulation is best, I used crocodile clips and enamelled wired, which is also called magnet wire
- A Battery
- An Iron Nail - as used in my 'How To Copper Coat An Iron Nail' video see that here.
- Iron filings
- Paper clips
Step 2: Coil The Wire
Step 3: Making the magnet stronger
To make electromagnets stronger we must do the following:
- Add more windings
- Give it an iron core
- Increase the current flowing through the wire
Step 4: Make Your Own Iron Filings
One piece of safety advice, don’t leave your battery in a position where it or the leads attached to it could come into contact with the iron filings. As they are very small, if electricity runs through them they will get super hot and burn.
