Solenoid S1 has N1 turns, radius R1, and length ℓ. It is so long that its magnetic field is uniform nearly everywhere inside it and is nearly zero outside. Solenoid S2 has N2 turns, radius R2 < R1, and the same length as S1. It lies inside S1, with their axes parallel. (a) Assume S1 carries variable current i. Compute the mutual inductance characterizing the emf induced in S2. (b) Now assume S2 carries current i. Compute the mutual inductance to which the emf in S1 is proportional. (c) State how the results of parts (a) and (b) compare with each other.

Solenoid S₁ has N₁ turns, radius R₁, and length ℓ. It is so long that its magnetic field is uniform nearly everywhere inside it and is nearly zero outside. Solenoid S₂ has N₂ turns, radius R₂ < R₁, and the same length as S₁. It lies inside S₁, with their axes parallel. (a) Assume S₁ carries variable current i. Compute the mutual inductance characterizing the emf induced in S₂. (b) Now assume S₂ carries current i. Compute the mutual inductance to which the emf in S₁ is proportional. (c) State how the results of parts (a) and (b) compare with each other.
