Mutual inductance is a measure of the extent to which the magnetic field generated by one coil links with the other coil. It is denoted by the symbol M. In this problem, we are given two coils with self-inductances of 9 mH and 4 mH respectively, and we need to find their mutual inductance.
The formula for mutual inductance is given by:
M = √(L1 * L2)
where L1 and L2 are the self-inductances of the two coils.
Given that L1 = 9 mH and L2 = 4 mH, we can substitute these values into the formula to find the mutual inductance:
M = √(9 * 4) = √36 = 6 mH
Therefore, the mutual inductance between the two coils is 6 mH.
To summarize:
- Given coils with self-inductances of 9 mH and 4 mH.
- Mutual inductance is a measure of the extent to which the magnetic field generated by one coil links with the other coil.
- The formula for mutual inductance is M = √(L1 * L2).
- Substituting the given values, we find that the mutual inductance is 6 mH.
