What is electromagnetic induction?

Electromagnetic induction is the production of an electromotive force (voltage) across an electrical conductor in a changing magnetic field. This phenomenon is fundamental to devices like generators and transformers.

How is self-inductance measured?

Self-inductance is typically measured in Henries (H). It quantifies how much voltage is induced in a coil due to a change in its own current.

What is mutual inductance?

Mutual inductance describes the magnetic coupling between two coils. A changing current in one coil induces an EMF in the other coil.

Why is wire thickness important in transformers?

Thicker wires have lower electrical resistance. In transformers, this helps to minimize power loss due to heating (Joule heating), leading to higher efficiency.

What is the relationship between induced EMF and rate of change of current?

According to Faraday's Law of Induction, the induced EMF is directly proportional to the rate of change of magnetic flux, which in turn is proportional to the rate of change of current in a coil.

How can soft iron enhance inductance?

Soft iron has a high relative permeability, meaning it can significantly increase the magnetic field strength within a solenoid. This amplification boosts both self and mutual inductance.

Are these MCQs suitable for the ENGINEERING 2026 exam?

Yes, these MCQs are designed with the ENGINEERING 2026 syllabus in mind. They cover essential concepts of electromagnetic induction that are frequently tested.

What is Faraday's Law of Induction?

Faraday's Law states that the magnitude of the induced EMF in any closed circuit is equal to the rate of change of the magnetic flux through the circuit.
