What happens when an external magnetic field is applied to a chunk of ferro magnetic material?

• It eliminates a lot of the magnetic domains

• It creates more magnetic domains

• It changes the size of the magnetic domains

• It has no effect on the magnetic domains

What is the overall behavior of a magnet determined by?

• The temperature of the magnetic domains

• The size of the magnetic domains

• The alignment of the magnetic domains

• The color of the magnetic domains

What is the purpose of using magneto static energy in a magnet?

• To create giant magnetic fields around the magnet

• To reduce the amount of energy

• To increase the amount of energy

• To change the direction of the magnetic domains
