A 20 loop coil lies on a table top in a region where the magnetic field is verticallyupward and has a value of 30 Gauss. the field is reduced to zero in 50 sec. If theradius of each loop is 7.0 cm, what is the average induced emf in the coil (a) whilethe field is changing (b) before the field begins to change? (c) As viewed fromabove, is the induced e.m.f. in the coil clockwise or anticlockwise? [ 1 Gauss = 1x 10 – 4Tesla] |
