Question

What do you observe when the south pole moved slowly into the solenoid

Answer 1

Answer:

1. When the south pole comes closer to the plane of coil , the flux of magnetic field through the coil increases. An Electromotive force is induced in the loop in a direction so as to oppose the change in flux caused by the magnet. 2. When the north pole end of the magnet moes all the way through a coil, there is an EMF induced in the loop. This has three stages i) When the north pole is approaching towards the plane but is yet to cross, the EMF is positive ii) While the north pole is crossing the induced EMF is zero. iii) When the north pole has croosed and still continues to move, the EMF is negative
