Magnetism

If you break a bar magnet in half, each half:

• contains one magnetic pole

• becomes unmagnetized

• becomes a bar magnet with 2 poles

Magnetic field strength is:

• strongest away from the poles

• strongest closest to the poles

• the same along the entire magnet

The magnitude of the force acting on a moving charge through a magnetic field is not dependent on

• The amount of charge

• The strength of the magnetic field

• The direction of the magnetic field
