Question

what happened when I mix water electricity and magnet

Answer 1

Basically, the force between two magnets depends on how far apart they are and what angles they're turned at. Of course, if there is something else around exerting forces on the magnets, you might lose track of the direct force between them.

That happens if there's, say, a piece of iron between them. They magnetize the iron, so there's now another magnet around. Whether it makes the net force on each magnet bigger or smaller depends on how they are arranged.
