Question

Electro-magnetic induction is a current produced because of voltage production

(electro motive force) due to changing magnetic field. This either happens when a

conductor is constantly moving in a stationary magnetic field.

A student was doing an experiment to see the variation of magnetic field with distance

from centre of the coil. He obtained the following graph:

From the graph deduce which of the following statements is correct?

i) When the number of turns in coil are 4, the induced current is 0.2 A.

ii) When the number of turns in coil are 4, the induced current is 0.4 A.

iii) When the number of turns in coil are 4, the induced current is 0.6 A.

iv) There is not enough information to find the value of induced current​
