Questions
A rectangular loop of length l (l>d) is being pulled at a constant speed v, through a region of certain thickness d, in which a uniform magnetic field B is set up. The graph between position x of the right-hand edge of the loop and the induced emf E will be
detailed solution
Correct option is B
As x increases so increases i.e. induced emf (e) is negative. When loop completely entered in the magnetic field, emf = 0When it exit out x increases but decreases i.e. e is positiveTalk to our academic expert!
