Inductance

Figure 14.4 shows a coil of N2= turns and radius R2 > R1 surrounding a long solenoid of length l1= m, radius R1=m, and N1= turns. What is the mutual inductance of the two coils?


M= H

The current in the solenoid is changing at a rate of A/s, what is the magnitude of the emf induced in the surrounding coil?
emf= V

M=N2Φ21I1=(N2I1)(μ0N1I1l1)πR21=μ0N1N2πR21l1.
