A coil of wire of certain radius has 600 turns and a self inductance of 108 mH. What will be the self inductance of a similar coil, which has 500 turns?

A coil has an inductive reactance of 160 ohm at frequency of 50 hz. Calculate the self inductance of the coil.

Explain self induction of a coil and give its unit.

What is self Inductance of a coil ? Define coefficient of self Induction.

A current balance is a device to measure magnetic forces. It is constructed from two parallel coils, each with an average radius of 12.5 cm. The lower coil rests on a balance, it has 20 turns and carries a constant current of 4.0 A. The upper coil, suspended 0.314 cm above the lower coil, has 50 turns and a current that can be varied. The reading of the balance changes as the. magnetic force on the lower coil changes. What current is needed in the upper coil to exert a force of 1.0 N on the bottom coil?

How does the self inductance of an air coil change, when the number of turns in the coil is decreased?

If N is the number of trns in a coil, the value of self-inductance varies as

An air core solenoid of 80 cm length has 500 turns and its circular cross-section has a diameter of 2 cm, calculate the self inductance of the solenoid?
