Q.

In an AC generator, a rectangular coil of 100 turns each having area 14×10-2 m2 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 π=227)                        [2023]


Ans.

(1584)

ξmax=NABω

=100×14×10-2×3×360×2π60=1584 V
