Question

Where does the energy go if the current is induced in a perfect conductor?

Answer 1

The energy will simply transfer from one conductor to another or just vanishes away.

Answer 2

Let us rotate a closed circuit made of a copper coil in front of a magnet. This will generate an induced current and all the mechanical energy will be converted into heat through Joule effect. If the coil is made of a perfect conductor, there will be no Joule effect and the rotation of the coil will cost no energy. Right? But  1 - According to Lenz's law, the field of the induced current will still oppose itself to the motion of the magnet. So it WILL cost energy to overcome the force exerted by the field on the magnet.  2 - The acceleration of the electrons back and forth in the coil WILL cost energy too.  Plz mate mark it as brainliest
