What is the SI unit of mutual inductance?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Henry.

Mutual inductance describes the phenomenon where a changing current in one coil induces an electromotive force (EMF), or voltage, in an adjacent coil. It quantifies how effectively the magnetic field generated by one coil links with another. One Henry is defined as the mutual inductance when a current changing at one ampere per second in one coil induces an EMF of one volt in the other coil.
