What would increase the strength of an electromagnet?

• Increasing the amount of current flowing through the wire.
• Inserting a wooden core inside the coil
• Changing the direction of the current
• Decreasing the number of coils of wire

• 30 coils will hold 50 paperclips
• Using more coils increases the strength of the electromagnet
• 15 coils hold twice as many paperclips as 10 coils
• The more coils, the fewer paperclips the electromagnet will hold

This is a magnet made by an electric current

• temporary
• permanent
• electromagnet
• ferromagnet
