Two coils \(A\) and \(B\) are placed in a circuit. When current in the coil \(A\) changes by \(0.8\;A\) the magnetic flux in coil \(B\) changes by \(0.16\;Wb\). The mutual inductance between the coils is
358534
The physical quantity which is measured in the unit of \(Wb{A^{ - 1}}\) is
1 Self inductance
2 Mutual inductance
3 Magnetic flux
4 Both 1 and 2
Explanation:
Units of mutual inductance and self inductance are same, i.e., \(H\) or \(Wb/A\). \([M]=[L]=\dfrac{[\phi]}{[I]}\)

Two circular coils can be arranged in any of the three situations shown in the figure. Their mutual inductance will be
1 Maximum in situation (B)
2 Maximum in situation (A)
3 The same in all situations
4 Maximum in situation (C)
Explanation:
The mutual inductance between two coils depends on their degree of flux linkage. Here, the two coils in arrangement (A) are placed with their planes parallel. This will allow maximum flux linkage and hence maximum mutual inductance.

Two coils are placed close to each other. The mutual inductance of the pair of coils depends upon
1 The materials of the wire of the coils
2 Relative position and orientation of the two coils
3 The rates at which the current are changing in two coils
4 The currents in the two coils
Explanation:
Mutual inductance of the pair of coils depends on distance between two coils and geometry of two coils.
