A fixed 16.1-cm-diameter wire coil is perpendicular to a magnetic field 0.53 T pointing up. In 0.23 s , the field is changed to 0.19 T pointing down. Part APart complete What is the average induced emf in the coil?

Average induced emf will be equal to 0.00156 volt

Explanation:

We have given diameter of the wire d = 16.1 cm

So radius

Cross sectional area of the wire

Magnetic field is changing from 0.53 T to 0.19 T

So change in magnetic field dB = 0.19-0.53 = -0.34 T

Time taken to change in magnetic field dt = 0.23 sec

Induced emf is given by

So average induced emf will be equal to 0.00156 volt
