Experiments with magnets and our surroundings

Magnetic fields

Two bar magnets end to end, N to S, with a gap between them

Here are some better details of two magnets, with the N and S facing each other.

The North poles are to the the right for each magnet.

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.
