Solution

The correct option is D

Ratio of magnetic flux produced by the coil 1 at the place of the coil 2 and the current in the coil 2 will be different from that of the ratio defined by interchanging the coils.


The explanation for the correct option

"When two coils are brought in proximity with each other the magnetic field in one of the coils tends to link with the other. This further leads to the generation of voltage in the second coil. This property of a coil which affects or changes the current and voltage in a secondary coil is called mutual inductance."

Magnetic induction depends upon the magnetic permeability μr of the medium between the coils or the nature of the material on which two coils are wound.

Hence, ‘option B' is correct.

Also,ϕ12I2ϕ21I1 is a true statement.

where, ϕ12 is the magnetic flux of the coil 1 at the place of the coil 2

ϕ21 is the magnetic flux of the coil 2 at the place of the coil 1

and I1, I2 is current in coil 1 and 2 respectively.

Hence, ‘option D’ is correct.

The explanation for the incorrect option:

Option A: The mutual inductance depends on the geometry of the two coils involved.

Option C: The mutual inductance is dependent on the magnetic property of the material.
