Mini-Quiz: Classifications of Magnetic Materials

by Ron Kurtus (updated 23 March 2012)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why shouldn't you heat a magnet to high temperatures?

It could become a Curie material

The magnet might levitate

It could lose its magnetism, if the temperature was high enough

2. Why doesn't aluminum stick to a magnet?

The attraction is extremely weak

Aluminum includes Teflon, which will not stick

Aluminum magnets are very common

3. Is it possible to magnetically levitate a small animal?

Only metals can be levitated

If the animal is lighter than air

Yes, since organic material is diamagnetic

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
