The self induction does not depend upon:
Correct answer: B. Weight of coil
- A. Core material
- B. Weight of coil
- C. Number of turns of the coil
- D. Area of coil
Explanation
The self-inductance of a coil does not depend upon the weight of the coil.Self-inductance is primarily determined by the physical properties of the coil itself, such as the number of turns, the geometry of the coil, and the permeability of the surrounding medium (if present). The weight of the coil, which relates to its mass, does not directly affect the self-inductance.

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.
