Figure shows a short solenoid of length 4 cm, radius 2.0 cm and number of turns 100., lying inside on the axis of a long solenoid, 80 cm long and number of turns 1,500. What is the flux through the long solenoid, if a current of 5.0 A flows through the short solenoid? Also obtain the mutual inductance of the two solenoids.
