Here, m = N1XN2Xmuxarea/length.

What about the formula for Mutual inductance = ((mu)N1N2A)/L. Mutual inductance don't depend on current at all right?

But probably figured that mutual induction used in this context is different from mutual inductance.

According to faraday's law of electromagnetic induction whenever current flowing through the primary winding of the transformer changes also changes the flux produced by it and when this change in flux links with the secondary winding emf get induced in secondary winding.

Is there any dependance on winding ratios?

Mutual inductance occurs when the change in current in one inductor induces a voltage in another nearby inductor.

Mutual inductence used at transformer because change in current in one coil automaticaly that current induces in another coil (faraday law).
