About formulas and math. Yes, you are right, it is difficult sometimes to explain complex phenomena without math. But, frankly I do not know how to explain existence of magnetic field without using relativity - because magnetic field is there only due to space contraction, it just is an electric field of a moving charge.

Simplified picture is as follows. As a charge moves, space contracts (for non-moving observer), and he sees more dense electric field near the equator of the charge than near the poles (if the chage moves in polar direction). This difference of an electric field of moving charge (compared to non-moving)is what we call a "magnetic field". So magnetic field is just a relativistic part of electric field of MOVING charge.
