Magnetization of rails by a moving field source

An experimental study is made of the process of magnetization of rails by a source of constant, square-shaped, magnetic field in translational motion. The experiments were carried out at velocities from 0 to 25 km/hr. It is shown that the rail magnetization at a given velocity depends entirely on the accompanying magnetic phenomena: the motion hysteresis, the inconsistent stepwise inversions, and the remanent magnetization.
