PhysicsEasysingle choice

An emf is generated by an ac generator having 100 turn coil, of loop area $1 m^{2}$ . The coil rotates at a speed of one revolution per second and placed in a uniform magnetic field of $0.05 T$ perpendicular to the axis of rotation of the coil. The maximum value of emf isNEET 2023 (Manipur)

Options:

Answer:

Solution:

Maximum value of emf generated by an ac generator is given by $ε_{0} = NBA ω = 100 \times 0.05 \times 1 \times 2 π = 31.415 V \approx 31.4 V$
