On loose leaf, answer the following questions using your notes, textbook and the internet:
1) Do magnets have to touch each other in order to experience a magnetic force? Explain.
2) What is the difference between a permanent and a temporary magnet?
3) If I want to know the direction of a magnetic field around a permanent magnet, what should I do?
4) A strong magnet in a junkyard can lift a car; what does this tell you about the relative strength of the magnetic and gravitational forces on the car? What do you think creates this magnetic force?
Also, mess around with this (use all the tabs at the top - it's awesome!):
