Question

A 20 loop coil lies on a table top in a region where the magnetic field is verticall upward and has a value of 30 Gauss. the field is reduced to zero in 50 sec. If th radius of each loop is 7.0 cm, what is the average induced emf in the coil (a) whil the field is changing (b) before the field begins to change? (c) As viewed fror above, is the induced e.m.f. in the coil clockwise or anticlockwise? [ 1 Gauss x 10 - Tesla]​

If the radius of each loop is 7.0 cm, what is the average induced emf has a value of 30 Gauss. the field is reduced to zero in 50 sec  upward and has a value of 30 Gauss. the field is reduced to zero in 50 sec.
