VIBRATION OF AC INDUCTION ELECTRIC MOTORS
... The rotor laminations are skewed to provide smoother torque The rotor does not quite keep up with the rotating magnetic field of the stator, however. It falls behind or slips as the field rotates. Motor slip is necessary for so that the shaft can supply useful torque. Another type of AC induction mo ...

Faraday paradox
This article describes the Faraday paradox in electromagnetism. There are many Faraday paradoxs in electrochemistry: see Faraday paradox (electrochemistry).The Faraday paradox (or Faraday's paradox) is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes:1. Faraday's law predicts that there will be zero EMF but there is a non-zero EMF.2. Faraday's law predicts that there will be a non-zero EMF but there is a zero EMF.Faraday deduced this law in 1831, after inventing the first electromagnetic generator or dynamo, but was never satisfied with his own explanation of the paradox.
