by Ron Kurtus (18 September 2016)

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

1. What is the requirement on the magnetic poles for the simple force equation?

They are only north seeking poles

They are quite large

They are considered points without areas

2. What happens to the force of repulsion when the magnet poles get closer?

The force gets smaller

The force increases

It is 4 times the other distance

3. How can the force equation apply to a magnet and iron nail?

The nail becomes slightly magnetized, such that the equation applies

Magnets do not attract iron nails; they only repel them

You need to know the size of the nail

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.
