Where on earth did you ever get the idea that magnets are based on "E=MC^2"? Probably went to one of those progressive schools that never taught you to think for yourself....
Magnets can store energy in the form of the magnetic field, but they cannot create it. The energy stored in the magnetic field has to come from somewhere when the field is created.
In the case of a lodestone (naturally magnetized material), the energy to magnetize the loadstone came from the earth's magnetic field, which in turn is created by the movement of molten metals in the earths core and the earth's rotation.
In the case of a man-made magnet, the energy stored in the magnetic field comes from whatever mechanism is used to magnetize the material in the first place, usually electricity.
