FTP, name this law which will indicate the direction of  the current induced by a permanent bar magnet pushed and  withdrawn through a coil of wire.
An extension of LeChatelier's principle into electromagnetic  theory, this law was deduced in 1834 by the Estonian physicist  for whom it is named. It states that an electric current induced  by a change in the magnetic field always flows in the direction  that will produce a field to oppose the change that produced the  current.
