A loop cell lies on a table top in a region where the magnetic field is vertically upward and has a value of
30 Gauss, the field is reduced to zero in 50 sec. If the radius of each loop is 7.0 cm, what is the average
induced emf in the coil (a) while the field is changing (b) before the field begins to change? (e) As viewed
from above, is the induced e m.f. in the coil clockwise or anticlockwise? [1 Gauss = 1 * 10 Tesla​
