Magnetic Fields Produced by a Conductors
... Magnetism is the force of attraction or repulsion of a magnetic material due to the arrangement of its atoms, particularly its electrons. Like poles will repel, opposite poles will attract. Magnetic field lines describe the structure of magnetic fields in three dimensions. At the poles of a magn ...
