WebThis is hardly surprising since opposites attract and likes repel is a common mantra of the science classroom. The same pattern of attraction and repulsion is found both for magnets and for electrically charged objects. Two like poles (two norths or two souths) repel each other, whilst opposite poles, a north near a south, attract. WebMagnetic fields occur whenever charge is in motion. As more charge is put in more motion, the strength of a magnetic field increases.
