Mention the energy transformation in transformer and induction coil.

Hi,

Please find below the solution to the asked query:

There is no energy changes in transformer. But, there are some loss of energy in the form of heat through iron core.  If we brought a magnet near to the induction coil, it induces current in the coil. Thus, in induction coil, kinetic energy of magnet get changed into electric energy.

Hope this information will clear your doubts about the topic.
