virtually induced emf.

static induced emf.

dynamically induced emf.

None of the above

Correct Answer : Option (B) : static induced emf.

Explanation : According to the Faraday's law of electromagnetic induction principle, the emf will be induced whenever conductor cuts a varying field or vice versa. The emf will be induced when an alternating magnetic field cuts the rotor conductor.
