QUIZ

Self-check your understanding

Why shouldn't you heat a magnet to high temperatures?
It could become a Curie materialSorry, not correct. Try another button. The magnet might levitateGood try, but not right. Select another answer. It could lose its magnetism, if the temperature was high enoughThat is correct. You are improving every day.
Why doesn't aluminum stick to a magnet?
The attraction is extremely weakCorrect. You did great. Aluminum includes Teflon, which will not stickOops! Wrong answer. Re-read the question and try again. Aluminum magnets are very commonSorry, not correct. Try another button.
Is it possible to magnetically levitate a small animal?
Only metals can be levitatedGood try, but not right. Select another answer. If the animal is lighter than airOops! Wrong answer. Re-read the question and try again. Yes, since organic material is diamagneticThat is correct. You are improving every day.

Pick an answer to see instant feedback. Re-read the lesson if you miss one.

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.
