The value of mutual inductance can be increased by
The value of mutual inductance can be increased by
- A. decreasing N
- B. increasing
- C. winding the coil on wooden frame
- D. winding the coil on china clay
Step-by-step solution
Mutual inductance is directly proportional to the number of turns in the coils. Increasing the number of turns increases the mutual inductance, while decreasing it reduces it. Winding coils on non-magnetic materials like wood or china clay does not enhance mutual inductance, as they have low permeability.
