Question

In an ac generator, a rectangular coil of $100$ turns each having area $14 \times 10^{-2} m ^2$ is rotated at $360\, rev / min$ about an axis perpendicular to a uniform magnetic field of magnitude $3.0 T$ The maximum value of the emf produced will be ________ $V$
(Take $\pi =\frac{22}{7}$)

Answer 1

The correct answer is 1584.
ξmax​=NABω
=100×14×10−2×3×60360×2π​
=1584V
