Experiments with magnets and our surroundings
What do magnetic fields look like?
Two bar magnets end to end, N to N, with a gap between them
Here are some better details of two magnets, with the N and S facing each other.
The North pole is on the right of the left hand magnet, and on the left of the right hand magnet. The North poles are facing each other. You can see how the fields are like springs that want to push the magnets apart.
This shows the magnetic field strength around these two magnets. It is zero in the center between the two magnets, where the fields are opposing each other. It is strongest at the corners of the surfaces that face each other.
