This is what happens when magnets repel.
What is they are pushed away from each other?
300

the  region around or space around a magnet where the effects of the magnets can be experience.

magnetic field

300

The greater the distance between two magnets, this happens.

 the weaker the attraction or repulsion

When you put a S and a S pole together they repel. This is what you feel.
What is the magnet force pushing against you?
400

Every magnet has these.

north and south poles

I have two magnets. The "N" side of the first magnet is facing the "N" side of the second magnet, what will happen to these magnets.

repulsion, they will repel
