A circular coil of radius a and having N turns is placed at centre of a long solenoid, coaxially. The solenoid has radius b ( b gtgt a ) and number of turns per unit length is n. Their coefficient of mutual inductance will be -

A circular coil of diameter 2 cm and 100 turns is placed at the centre of a long solenoid of radius 5 cm and 10 turns//cm . The mutual inductance of the two coils will be nearest to:

A circular coil with a cross-sectional area of 4 cm^(2) has 10 turns. It is placed at the centre of a long solenoid that has 15 truns/cm and a cross-sectional area of 10 cm^(2) . The axis of the coil coincides with the axis of the solenoid. What is their mutual inductance?

A circular coil with a cross-sectional area of 4cm^(2) has 10 turns. It is placed at the center of a long solenoid that has 15 turns/cm and a cross sectional area of 10cm^(2) , shown in the figure. The axis of the coil conicides with the axis of the solenoid. What is their mutual inductance?

A long slenoid of radius 2 cm has 100 turns/cm and carries a current of 5A. A coil of radus 1 cm having 100 turns and a total resistance of 20 Omega is placed inside the solenoid coxially. The coil is conneted to a galvanometer. If the current in the solenoid is reversed in direction, find the charge flown through the galvanometer.
