If a 200 turn, 10-3 m2 cross-sectional area coil is immersed in a magnetic field such that the plane of the coil is perpendicular to the field. If the magnetic field increases by 6 T/s, then how much voltage is induced

Explanation:

Given:

Number of turns

Cross sectional area

Rate of increasing magnetic field

From the faraday's law,

Induced emf is given by,

Where magnetic flux

           ( because angle between normal coil and field is zero)

Where area of coil

Put the value of in above equation,

Here we neglect minus sign

    V

Therefore, 1.2 volt induced in coil
