(a) Assume solenoid 1 carries variable current I . Compute the mutual inductance

Question

(a) Assume solenoid 1 carries variable current I. Compute the mutual inductance characterizing the emf induced in solenoid 2. (Use any variable or symbol stated above along with the following as necessary: ?0 and ?.)

M12 =

(b) Now assume solenoid 2 carries current I. Compute the mutual inductance to which the emf in solenoid 1 is proportional. (Use any variable or symbol stated above along with the following as necessary: ?0 and ?.)

M12 =

(c) State how the results of parts (a) and (b) compare with each other.

The mutual inductances are the same. The mutual inductances are different.     

Please Help, please answer in detail and step by step for rating!

Thanks         

Explanation / Answer

M12xi=u0N1N2Ai/length

i will get cancelled for any current value...

therefore, M12=M21

M12=u0N1N2x3.14xR2^2/length = M21 (since R2<R1)
