Question
As illustrated in the figure below, a bar magnet was initially held stationary inside an inductor for a long time, and then released and the magnet fill out of the inductor by the action of the Earth's gravity. The inductor is made out of circular loops of wires. The number of turns in the inductor is N, the self inductance of the inductor is L, and the inductor is much bigger than the size of the magnet in both the length and the diameter. The voltage V_L across the inductor was measured from the moment the magnet was released. Choose all that are correct from the following.Explanation / Answer
On moon rate of falling will decrease as acceleration due to gravity is less so rate of change of flux will also decrease
hence option 1 can not be true
VL depends on inductacne so option B is correct
Third option is correct because more magnetic field will change per unit time
Fourth option is also correct as L is proportional to N
