A square loop of side $15 cm$ being moved towards right at a constant speed of 2 $cm / s$ as shown in figure. The front edge enters the $50 cm$ wide magnetic field at $t =$ 0 . The value of induced emf in the loop at $t = 10 s$ will be :

Options:

Answer:

Solution:

At $t = 10 sec$ complete loop is in magnetic field therefore no change in flux $e = \frac{d ϕ}{dt} = 0$ $e = 0$ for complete loop
