Physics-Self & Mutual Induction
NEET Physics Self & Mutual Induction MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about self and mutual induction is correct?
A
Self-induction occurs when a changing current in a coil induces emf in the same coil.
B
Mutual inductance is independent of the geometrical configuration of the coils.
C
The self-induced emf in a coil increases with a decrease in the current through it.
D
Mutual induction only occurs in coils that are not physically adjacent to each other.
Correct Answer
Option A
Detailed Explanation
Self-induction is indeed the phenomenon where a changing current in a coil induces an emf within the same coil, as described in the context. The other statements reflect common misconceptions about mutual inductance and self-induction.
