Magnetism is still a big mystery. This is due to the fact that the source of it cannot be found, the magnetic monopoles. It can be theorized that magnetism is the key to understanding the concept of perpetual motion. It seems that the magnetic field is always in motion. This motion is nonstoppable. It detection can be seen by the presence of charged particles in the field. But how fast is the field moving can only be guessed. The strength of the field is determined by the radius of spiral of the charged particles moving along the field lines of force. If the speed of the field is directly proportional to the speed of the field, then when the radius of the spiral is almost zero, the field is moving at near maximum speed. Is this the speed of light?
