Transformer works on the principle of:
Correct answer: C. Magnetic induction
- A. Lenz's law
- B. Faraday's law
- C. Magnetic induction
- D. Ampere's law
Explanation
Magnetic induction, also known as electromagnetic induction, is the fundamental principle behind the operation of transformers. According to this principle, when the current in the primary coil of a transformer changes, it creates a changing magnetic field. This changing magnetic field induces a voltage in the secondary coil of the transformer, which results in the transfer of electrical energy between the primary and secondary coils.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
