Question

Suppose that you have a circular magnetic field ‘B’ of radius R = 9.0 cm, pointing inside the page and if this field is increased at the rate dB/dt = 0.15 T/sec. calculate (a) the magnitude of induced electric field at a point within the magnetic field at a distance r =5.0 cm, from the center of the field and (b) the magnitude of the induced electric field at a point out side the magnetic field at a distance r = 12.0 cm

Answer 1

For r = 5 cm

E = 3.75 10^-3 V/m

For r = 12 cm

E = 5.06 10^-3 V/m
