Question

A student connects a battery to a wire and wraps the wire around an iron nail to produce an electromagnet. Which action should the student take to increase the number of paper clips the electromagnet can pick up?(1 point) Responses He should reduce the number of turns. He should reduce the number of turns. He should add another battery. He should add another battery. He should replace the iron nail with a plastic spoon. He should replace the iron nail with a plastic spoon. He should decrease the current through the wire.

Answer 1

To increase the number of paper clips that the electromagnet can pick up, the student should add another battery. This will increase the current flowing through the wire, which in turn will strengthen the magnetic field created by the electromagnet, allowing it to pick up more paper clips.

The other options, such as reducing the number of turns or replacing the iron nail with a plastic spoon, would not help in making a stronger electromagnet. Decreasing the current would also weaken the magnetic field. Therefore, the best option is to add another battery.
