A coil is rotated in a uniform magnetic field about an axis perpendicular to the field. The emf induced in the coil would be maximum when the plane of coil is :

A coil is rotated in a uniform magnetic field about an axis perpendicular to the field. The emf induced in the coil would be maximum when the plane of coil is :

When a rectangular coil is rotated about an axis in the plane of coil and perpendicular to magnetic field with steady speed then

A rectangular coil of 200 turns or wire 15 xx 40 cm^(2) makes 50 r.p.s. about an axis in its plane parallel to its longer side and perpendicular to a magnetic field of intensity 0.08 Wb//m^(2) . What are the instantaneous values of induced e.m.f. when the plane of the coil makes an angle with magnetic field of (a) 0^(@) (b) 60^(@) (c) 90^(@) ?
