Q6.10Multiple correct
A circular coil expands radially in a region of magnetic field and no electromotive force is produced in the coil. This can be because
- (a)the magnetic field is constant.
- (b)the magnetic field is in the same plane as the circular coil and it may or may not vary.
- (c)the magnetic field has a perpendicular (to the plane of the coil) component whose magnitude is decreasing suitably.
- (d)there is a constant magnetic field in the perpendicular (to the plane of the coil) direction.
