MCQ
The value of mutual inductance can be increased by.
- Adecreasing $N$
- ✓increasing $N$
- Cwinding the coil on wooden frame
- Dwinding the coil on china clay
✓
Answer
Correct option: B.
increasing $N$
$\text{M}=\mu\text{N}_1\text{N}_2\frac{\text{Area}_{12}}{\text{length}_{12}}$
Area$_{12} -$ area in common to both the coils where the flux links both of them together.
length$_{12} -$ length in common to both the coils where the flux links both of them together.
Therefore to increase the mutual inductance, the number of turns can be increased.
