Question

How can I calcualte this?(Magnetic interactions between two magnets?)

How is it possibile to calcualte the force generated by to magnets attracting each other and repelling each other?

What I've understood so far is that a magnetic fields generate an electrical field that indeed does work on the magnets to attract or repel each other. Now how can I calcualte:

1) The force generated by two magnet's attracting/repelling each other.
2) How can I calculate the electrical force created by the magnetic field of the magnet?

Also I'd like to add that the magnets are in a non-uniform magne
