Understanding and Dealing with Ferroresonance
... of the transformer core represented by LM. The nonlinearity involved makes it impossible to predict whether ferroresonance will occur or not, and if so how severe the overvoltage will be. More than one mode of ferroresonance is possible, and operation may jump in and out of ferroresonance depending ...

... Current flows through the wire coil and creates an electromagnet. One face of the coil becomes a north pole, the other a south pole. The permanent magnet attracts its opposite pole on the coil and repels its like pole, causing the coil to spin. Another way to describe the operation of the motor is t ...
