Could a current be induced in a coil by rotating a magnet inside the coil? If so, how?

state the rule to determine the direction of a current induced in a coil due to its rotation in a magnetic field.

A circular coilof radius 0.157 m has 50 number of turns. It is placed such that its axis is in magnetic meridian. A dip needle is supported at the centre of the coil with its axis of rotation horizontal, and in the plane of the coil. The angle of dip is 30^(@) when a current flows through the coil. The angle of dip becomes 60^(@) on reversing the current. Find the current in the coil assuming that the magnetic field due to the coil is smaller than the horizontal component of earth's magnetic field, H =3xx10^(-5) T.

Figure shows three different orientations of a circular coil rotating in the magnetic field between the poles of a horse shoe magnet. Determine the direction of induced current in the coil, if the rotation is anticlockwise as viewed by the reader.

Figure shows three different orientations of a circular coil rotating in the magnetic field between the poles of a horse shoe magnet. In which orientation during rotation with uniform angular speed) is the induced e.m.f. greatest?

State the factors on which induced e.m.f. in a coil rotating in a uniform magnetic field depends.
