A square coil of 20 cm side and with 200 turns is rotated at a uniform velocity of 10 m/s about an axis at right angles to a uniform magnetic field having a flux density of 0.5 T. Determine the instantaneous value of the induced emf when the plane of the coil is in the plane of the field.
An instrument always extracts some energy from the measured medium. Thus the measured quantity is always disturbed by the act of measurement, which makes a perfect measurement theoretically impossible and it is due to
Directions: Each of the next items consists of two statements, one labeled as the `Assertion (A)' and the other as 'Reason (R)' You are to examine these two statements carefully and select the answers to these items using the codes given below :Assertion (A) : For time varying field the relation E̅ = - ∇̅ V is inadequate. Reason (R): Faraday's law states that for time-varying field ∇̅ × E̅ = 0.
