The arm PQ of a rectangular conductor is moving from x = 0 to x = 2b outwards and then inwards from x = 2b to x = 0 as shown in the figure. A uniform magnetic field perpendicular to the plane is acting from x = 0 to x = b. Identify the graph showing the variation of different quantities with distance:
Text Solution
Verified by ExpertsThe correct answer is:
C
As rod moves in field area increases upto 
n then field is absent and again flux is generated on return journey from x = b to x = 0. Thus plot A for flux.
curve B for emf
Power dissipated = vi
curve C for power dissipated
