*If it won't pick up the paper clip:
-Make sure the battery is working.
-Tap the electromagnet on the ground. This helps to align the mini-magnets.
-Make sure the bolt is one that can be magnetized. To test this, see if it is attracted to an existing magnet.
-The wire should be wrapped tightly around the bolt, totaling around 50-60 loops.
-The paper clip may be too heavy. Use a lighter paper clip or break part of it off.
*How can we make the electromagnet stronger?
-By increasing the electricity running through the wire, or the number of loops of wire around the bolt, the strength of the electromagnet is increased.
Warning: The electromagnet gets hot. The more electricity running through, the faster and hotter it gets. A fresh 1.5V is enough to pick up a paperclip. With this battery your electromagnet will get warm after about 5 minutes but won't cause any harm. Hooking up multiple batteries and leaving them connected for a long time could cause trouble, so don't.
