Maxwell collected various rules relating to electromagnetic theory by presenting a summary in the form of equations, math, which Maxwell used predict the electric changes depending on the time. Cause a magnetic field, and at the same time, the changing magnetic field, caused by electric by electric and magnetic field direction is perpendicular to each other, are also predicted that waves Maxwell Electromagnetic induction caused by continuously between the worth I.Mamae and magnetic field causes the electric and magnetic field moving out from the origin of electromagnetic waves in a vacuum move with speed equal to the speed of light, so the light idea that Maxwell is an electromagnetic wave whose frequency range, this prophecy was confirmed as true by the experiments of Hertz.
