When a current flows through a wire, a magnetic field is produced around the wire.

The magnetic field produced around a current carrying wire varies in strength depending on the position relative to the wire and the speed of the current in the wire.

1

The magnetic field lines travel around the wire in circles. Is this statement true?

2

Are the magnetic field lines movements parallel or perpendicular to the wire?

3

Which hand is used for the rule that allows us to see which direction the magnetic field travels in?

4

If the direction of the current is reversed, what effect does this have on the magnetic field?

5

Does the magnetic field get stronger or weaker as you move away from the wire?
