Question

In mutual induction
A: when current in one coil increases, induced current in neighbouring coil flows in the opposite direction
B: When current in one coil decreases, induced current in neighbouring coil flows in the opposite direction

• A. A is true, B is false
• B. A and B are false
• C. A and B are true
• D. A is false, B is true

Answer 1

The correct option is A A is true, B is false

When this emf is induced in the same circuit in which the current is changing this effect is called Self-induction, ( L ). However, when the emf is induced into an adjacent coil situated within the same magnetic field, the emf is said to be induced magnetically, inductively or by Mutual induction, symbol ( M ).

In mutual induction when current in one coil increases, induced current in neighbouring coil flows in the opposite direction
