Which of the following is true of all magnets?

• They are man-made.

• They are made of iron.

• They have two poles and a magnetic field.

• They are magnetic only when an electric charge goes through them.

If you have two magnets and you try to put the two north poles together, what will most likely happen?

• The two poles will not touch each other because of magnetic repulsion.

• The magnets will stick together because of magnetic attraction.

• The two poles will touch but not stick together.

• The magnets will lose their magnetism.
