In an ac generator, a rectangular coil of 100 turns each having area 14 × 10 – 2 m 2 is rotated at 360 rev min - 1 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 = 22 7 ]

Correct answer

0

Step-by-step solution

Maximum value of induced EMF can be written as, ξ max = N A B ω = 100 × 14 × 10 - 2 × 3 × 360 × 2 π 60 = 1584   V
