The magnetic field strength between the poles of a strong electromagnetic at a given moment is b=0.10t. a circular coil of radius r=2.0cm qnd having 10 turns is placed within the field and perpendicular to it. the magnetic field strength increases steadily to 0.25t in 1.2ms. under these conditions :
a) calculate the magnetic flux in the coil initially and after 1.2ms.
b)calculate the emf induced in the coul while the field is changing.
c)if the axis of the coil has made an angle of 35° with the direction of the magnetic field, how would the induced emf have differed?
