- 1). Test the strength of the existing bar magnet by placing it in a box filled with paperclips. Count the number of paperclips attached to the magnet when the magnet is removed. This will provide a baseline as to how strong the magnet is.
- 2). Wrap copper wire around the middle section of the magnet. Wrap the wire into as tight a coil around the center as possible, leaving 6 to 8 inches worth of copper wire exposed on each side of the magnet.
- 3). Connect each end of the copper wire to the poles of the 6 volt battery to create an electromagnet.
- 4). Retest the magnet by dropping it back into the box of paperclips. Count the amount of paperclips still attached to the electromagnet.
- 5). Remove the copper wire from the battery and the magnet.
- 6). Test the magnet again to see if the electricity increased the strength of the magnet, even after it had been removed. Count the paperclips attached to the magnet.
