You will need:

• Batteries: one 9V, one 6V, one 1.5V
• Battery terminals
• One 60cm insulated wire length
• One 20cm long Steel rod
• Paperclips or measured iron weights

1

Strip 2cm off both ends of the insulated wire

2

Wrap the wire tightly around the iron bar, keeping the wire loops next to each other. Do this at least 40 times!

3

Connect the ends of the wire to the battery terminal and connect the battery.

4

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

5

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.

### Variables to test

More on variables here

• What happens if you wind the coil of wire the opposite way?
• What happens when you change the battery voltage (do not exceed 9V)
• Does the thickness of the wire make a difference?
• What happens if you use uninsulated wire instead?
