The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
The strong force is the real glue of the nucleus. It first holds the quarks together within protons and neutrons. Being 137 times more powerful than the electromagnetic force, the aptly named strong force also holds the protons and neutrons together within the nucleus, overwhelming their electromagnetic repulsion. The weak force is less powerful than the electromagnetic force, but still plays an important role in nuclear processes.
