Tell how to make a temporary magnet using electricity

You'll need an iron nail, copper wire, a D-cell battery, paper clips or pins, and masking tape.

wrap the copper wire around the nail downward. then wrap one end of the exposed wire around the positive side of the battery and the other end around the negative side of the battery and use the tape to hold them together. place the nail near the paper clip/pin. you can experiment with different sizes too, but this should work (:

You can make a temporary magnet by stroking a piece of iron or steel (such as a needle) along a permanent magnet. There is another way that uses electricity to make a temporary magnet, called an electromagnet.
