NEET2023PhysicsElectromagnetic InductionActual
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 is
Options
- A62.8 ~V
- B6.28 ~V
- C3.14 ~V
- D31.4 ~V
Correct answer
D. 31.4 ~V
Step-by-step solution
Maximum value of emf generated by an ac generator is given by aligned ₀ & = NBA & =100 0.05 1 2 & =31.415 ~V & 31.4 ~V aligned
