A straight solenoid of length `1 m` has `5000` turns in the primary and `200` turns in the secondary. If the area of cross section is `4 cm^(2)`, the mutual inductance will be

A straight solenoid of length 1m has 5000 turns in the primary and 200 turns in the secondary.If the area of cross-section is 4cm^(2) ,the mutual inductance will be

A straight solenoid has 50 turns per cm in primary and total 200 turns in the secondary. The area of cross section of the solenoids is 4cm^2 . Calculate the mutual inductance. Primary is tightly kept in side the secondary.

When the number of turns and length of a solenoid are doubled keeping the area of cross-section same, the inductance.

When the number of turns and the length of the solenoid are doubled keeping the area of cross-section same, the inductance

When the number of turns and the length of the solenoid are doubled keeping the area of cross-section same, the inductance

The number of turns of a solenoid of length l and area of cross-section A is N. The self-inductance L increases as
