A Low-Frequency Motionless Magnetic Antenna Based On Permanent Magnet

A new method is introduced for generating electromagnetic waves. In this proposed method, a permanent magnet is used as a flux source and its stored magnetic energy is then modulated by altering the reluctance of the surrounding material through time-varying electric current. This approach uses the nonlinear B-H curve of magnetic material to saturate and desaturate the magnet's surrounding environment resulting in a time-varying magnetic field.
