State one (1) similarity and one (1) difference between self-inductance andmutual-inductance

Similarity between Self-Inductance and Mutual-Inductance

1. Electromagnetic Principle: Both self-inductance and mutual inductance are phenomena that occur due to the principle of electromagnetic induction. They both involve the generation of electromotive force (emf) in a circuit due to changing magnetic fields.

Difference between Self-Inductance and Mutual-Inductance

1. Definition: Self-inductance refers to the property of a single coil or circuit to induce an emf in itself due to a change in current flowing through it. In contrast, mutual inductance describes the induction of an emf in one coil due to a change in current in a nearby coil.

In summary, both self-inductance and mutual inductance stem from electromagnetic induction, but they differ in their involvement with one coil (self) versus two coils (mutual).
