Experiments with magnets and our surroundings

What do magnetic fields look like?

Two bar magnets side by side, N by N, with a gap between them

Here are some better details of two magnets, with the N poles facing up.

Both of the North poles are up.  This is the same field for a ring magnet that has a hole in its center.  You can see how the two magnets don't want to be close to each other.

This shows the magnetic field strength around these two magnets.  It is concentrated in the space between the two magnets.  This is where the field lines are closer together.  This plot is almost identical to the field where the two magnets are pulling each other together.
