The current produced due to electromagnetic induction is called:
Correct answer: C. Induced current
- A. Electric current
- B. Conventional current
- C. Induced current
- D. All of above
Explanation
The current produced due to electromagnetic induction is specifically called Induced current.When a conductor is exposed to a changing magnetic field or when there is a change in the magnetic flux through the conductor, Faraday's law of electromagnetic induction states that an electromotive force (EMF) is induced in the conductor. This induced EMF drives a current to flow in the conductor if the circuit is closed. The current that flows as a result of this induced EMF is known as the induced current.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
