MCQ
Mutual inductance of two coils can be increased by
- ADecreasing the number of turns in the coils
- ✓Increasing the number of turns in the coils
- CWinding the coils on wooden core
- DNone of the above
✓
Answer
Correct option: B.
Increasing the number of turns in the coils
b
(b) Mutual inductance of coils,
(b) Mutual inductance of coils,
$M=\frac{\mu_{0} \mu_{r} N_{1} N_{2} A}{l}$
It is clear that mutual inductance or coils can be increased by increasing the number of turns in the coils
