A small single r=1mm is placed coaxially at the center of a long solenoid n=500 tunrs per cm. The solenoid carries a current i=7sin(wt) a) what is the magnetic field through the small coil? b) What is the flux though the small coil? c) What is the rate of change of flux through the small coil? d) what is the EMF in the small coil? E) What is the Mutual inductance M21 of the small coil(2) due to the current is solenoid?
