A rectangular loop of wire in the plane ...

A rectangular loop of wire in the plane of the paper starts outside a perpendicular uniform magnetic field directed into the paper as shown in the following figure. The loop is pulled with a constant velocity through the magnetic field and out the other side. Which of the following graphs would best represent the variation of the electric current in the wire with time?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D

As `e=(-dvarphi_(B))/dt`, Current (i) = `e/r`
r `to` is the resistance.
