The magnetic flux (Φ) through the area of cross-section of a current-carrying coil is proportional to the current (i) i.e., Φ = Li.
(A) L is self-inductance of the coil
(B) The self-inductance of the coil does not depend on its geometry
(C) self-inductance is the electromagnetic analogue of mass in mechanics
(D) The self-inductance of the coil depends on the permeability of the medium inside coil

Answer & Solution

Correct Answer

(B) (A), (C) and (D) only

Step-by-step Solution

Detailed explanation

(A) Correct: In the relation \(\Phi=L i, L\) is indeed the proportionality constant known as the self-inductance of the coil. (C) Correct: Self-inductance is often called electrical inertia. Just as mass resists a change in the state of motion in mechanics, inductance resists a…
