Try to pick up paperclips using the iron bar. How many can you pick up?

Does the size of the battery make a difference on the amount of weight you can pick up?

Does the size of the battery make a difference on the amount of weight you can pick up?

Why Does This Happen?

A magnetic field occurs when electricity passes through a wire.

This magnetic field surrounds the wire. Wrapping the wire in a tight coil concentrates the magnetic field in the centre of the coil. The magnetic field faces the same direction throughout the iron bar and you can pick up iron objects.
