What is NOT a way to increase the strength of an electromagnet?

• decrease the number of coils

• use a stronger battery

• use a stronger magnet

• increase the number of coils

How can you test to see if an electromagnet is stronger after adding more coils of wire?

• if it picks up fewer paperclips

• compass still points toward the electromagnet when moved further away

• if it picks up the same number of paperclips

• compass still points toward the electromagnet when moved closer
