Consider the self-inductance per unit length of a solenoid at its centre and that near its ends. Which of the two is greater?

Consider the energy density in a solenoid at its centre and that near its ends. Which of the two is greater?

Why the inductance per unit length for a solenoid near its centre is different from inductance per unit length near its ends?

A tightly- wound, long solenoid is kept with its axis parallel to a large metal sheet carrying a surface current. The surgace current through a width dl of the sheet is Kdl and the number of turns per unit length of the solenoid is n. The magnetic field near the centre of the solenoid is found to be zero. (a) find the current in the solenoid. (b) If the solenoid is rotated to make its axis perpendicular to the metal sheet, what would be the magnitude of the magnetic field near its centre?

Calculate the self inductance per unit length of a current loop formed by joining the ends of two long parallel wires of radius r separated by a distance d between their axes, neglecting the end effects and magnetic flux within the wires.

The self inductance L of a solenoid depends on the number of turns per unit length 'n' as

A solenoid have self inductance 2H. If length of the solenoid is double having turn density and area constant then new self inductance is :-

The self inductance of a solenoid of length L, area of cross-section A and having N turns is-

A conductor of length L is placed along the x - axis , with one of its ends at x = 0 and the other at x = L. If the rate of flow of heat energy through the conduct is constant and its thermal resistance per unit length is also constant , then Which of the following graphs is/are correct ?

If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will

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