For best answer I really need explanation for all. Thanks so much!
Question:-
A small bar magnet drops through a coil The magnet does not rotate during the fall. Assume that both the starting point and the end point are very far away from the coil.
a) What is the initial magnetic flux in the coil?
b) what is the final magnetic flux through the coil?
c) what is the net change of the magnetic flux in the coil
d) Would the falling magnet induce any voltage in the coil?
e) Does the induced voltage depend on the average magnetic flux change or on the instantaneous value of the magnetic flux change ?
Explanation / Answer
a) What is the initial magnetic flux in the coil?
as coil is very far away , FLux = ZERO
b) what is the final magnetic flux through the coil?
as coil is very far away , FLux is ZERO
c) what is the net change of the magnetic flux in the coil
Net change in Flux is ZERO as initial and final flux are both zero
d) Would the falling magnet induce any voltage in the coil?
Yes , it will induce a voltage in the coil
e) Does the induced voltage depend on the average magnetic flux change or on the instantaneous value of the magnetic flux change ?
the induced voltage depend on the instantaneous value of the magnetic flux change
