Question 82: Electromagnetic Induction

Question

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.

Accepted Answer

As the rectangular conductor moves in field area, so flux is increasing up to x = b, then flux is generated on return journey from x = b to x = 0. The flux is shown by plot A of the graph.
As, emf, $$e =  - {{d\phi } \over {dt}}$$, which is shown by curve B and power dissipated, P = VI which is shown by curve C.
