A rectangular conducting loop of length l and breadth b enters a uniform magnetic field B as shown below.

The loop is moving at constant speed v and at t = 0 it just enters the field B. Sketch the following graphs for the time interval t = 0 to `t = (3l)/(v)`.
(iii) Power versus time
Resistance of the loop is R.

Explanation

(iii) `P_(0) = (epsilon_(0)^(2))/(R ) = (B^2 v^2 b^2)/(R )`
