One solenoid is centered inside another. The outer one has a length of 55.0 centimeter and contains 6600 coils, while the coaxial inner solenoid is 5.00 centimeter long and 0.130 centimeter in diameter and contains 22.0 coils. The current in the outer solenoid is changing at 35.0 A/s.
Determine the mutual inductance of these solenoids? In μH
Determine the emf induced in the inner solenoid?
