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

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
