Answer #1

Answer :

An induced EMF may be generated in a loop of wire because of :

◉ any of the reasons mentioned in the answer boxes.

.

Because, According to Faraday's law of Electromagnetic induction : When the flux linked with the coil changes it will induce emf/Current in the closed loop.

The change in flux linked linked with the loop can be changed by all of the following means :

  • a magnetic pole moving away from it
  • an approaching magnetic pole toward it
  • variation of current through the wire
