Electromagnetic Induction

Question:

The magnetic flux through a coil perpendicular to its plane and directed into paper is varying according to relation  = 5t2 + 10t + 5 milli weber. The e.m.f. induced in the loop after 5 sec is

Options:

0.03V

0.06V

0.08V

0.02V

Correct Answer:

0.06V

Explanation:

$\xi = \frac{d\phi}{dt} = 10t+10 = 60\times 10^{-3} V = 0.06V$
