Question

why change in magnetic flux induces emf ? ​

Answer 1

Answer:

Whenever the flux passing through the coil changes by any way (like either changing angle, magnetic field or area of coil), we are actually producing a relative motion between electrons and magnetic field. As a result, the electrons experience a magnetic force and shift to produce EMF.

Answer 2

Answer:

Change in magnetic flux doesn't induces emf it is the time rate of change in magnetic flux which induces emf

Explanation: Change in time rate change of magnetic flux induces emf

Relative motion is generated between electrons due to which an emf is induced
