The direction of induced emf is determined by right hand rule. As per the the rule, if the thumb is pointed in the direction of motion of the conductor and the first finger is pointed in the direction of the magnetic field (north to south), then the second.
The direction of the induced e.m.f. can be determined by Fleming’s right hand rule . Induced E.m.f. in a coil rotating in a magnetic field Induced E.m.f. in a coil rotating in a magnetic field. Consider a rectangular coil being rotated with constant angular velocity (omega ) in the uniform magnetic field about an axis perpendicular to the field. Let, Lenzs law is used to determine the direction of induced emf in the conductor or coil. According to Lenz’s law, the electromagnetically induced emf and hence current flows in the conductor or coil in such a direction that the magnetic field set up by it always oppose the cause, which produces it.
For a given circuit, the electromagnetically induced emf is determined purely by the rate of change of the magnetic flux through the circuit according to Faraday’s law of induction. An emf is induced in a coil or conductor whenever there is change in the flux linkages.
Moves parallel to the magnetic field. Solution: An emf is induced, according to Faraday’s laws of electromagnetic inductance, whenever the conductor in a magnetic field cuts the magnetic lies of flux, varying the flux per unit area, and hence the magnetic field.

Induced emf (electromotive force) is defined as the potential difference induced in a (coil or a) conductor by the changing magnetic flux linking to it. The magnitude of induced emf depends on several factors such as, number of turns in coil (if it is a coil), length of the conductor moving, relative velocity between conductor and magnetic flux , and magnetic flux strength.
