Ellie made an electromagnet with wire, a nail, and a 2.5-volt battery. The electromagnet attracted a paper clip from 2 inches away.
What actions will make the electromagnet stronger?
a. She can use a thicker piece of wire.
b. She can use a higher-voltage battery.
c. She can wrap the wire more times around the nail.
d. She can decrease the number of coils around the nail.Ellie made an electromagnet with wire, a nail, and a 2.5-volt battery. The electromagnet attracted a paper clip from 2 inches away.

To make the electromagnet stronger, Ellie can use a thicker piece of wire, use a higher-voltage battery, or wrap the wire more times around the nail. These actions will increase the strength of the magnetic field produced by the electromagnet, resulting in a stronger attraction to the paper clip. Decreasing the number of coils around the nail would actually weaken the electromagnet, so that option should be avoided.
