What happens when a magnet is broken in half?

• Two magnets are created

• The magnet becomes weaker

• The magnet becomes stronger

• The magnet loses its magnetism

What is the purpose of having magnetic domains within magnets?

• To reduce the amount of energy

• To increase the amount of energy

• To create a stronger magnetic field

• To create a weaker magnetic field

What is lodestone?

• Naturally magnetized pieces of magnetite

• Artificially magnetized pieces of magnetite

• Naturally magnetized pieces of iron

• Artificially magnetized pieces of iron

How can a chunk of ferro magnetic material be magnetized in the laboratory?

• By putting it inside a magnetic field

• By putting it inside a gravitational field

• By putting it inside a nuclear field

• By putting it inside an electric field

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

How do magnetic domains lead to the overall behavior of the magnet?

• By aligning to create an overall magnetic field

• By pointing in every which direction

• By changing their size

• By separating from each other
