A square metallic wire loop of side 0.1 m and resistance of 1 Ω Ω is moved with a constant velocity in a magnetic field of 2 wb/m 2 as shown in figure. The magnetic field is perpendicular to the plane of the loop, loop is connected to a network of resistances. What should be the velocity of loop so as to have a steady current of 1mA in loop
Text Solution
Verified by ExpertsThe correct answer is:
B
Equivalent resistance of the given Wheatstone bridge circuit (balanced) is 
.
So total resistance in circuit is 
. The emf induced in the loop, 
.
So, induced current
