Q. A loop of area 0.1 $m^{2}$ rotates with a speed of 60 rps perpendicular to a magnetic field of 0.4 T. If there are 100 turns in the loop, maximum voltage induced in the loop is
A) 15.07 V
B) 1507 V
C) 250 V
D) 150 V
Explanation
(b) $e_{0} = nAB\omega$
= $100\ \times 0.1 \times 0.4\ \times (2\pi \times 60) = 150$V
