Experiments with magnets and our surroundings
Two bar magnets end to end, S to S, with no gap between them
Here are some better details of two magnets, with the N poles facing each other.
The North poles are in the middle, facing each other. This is very difficult to accomplish with NIB magnets using your bare hands.
This shows the magnetic field strength around the two magnets. It is strongest at the interface between the two.
