Question
The ratio of magnetic induction on the axis of a long straight current carrying solenoid at a point on the end to that at the centre of the solenoid(a) $1: 1$(b) $2: 1$(c) $1: 2$(d) $1: \sqrt{2}$
Step 1
Step 1: The magnetic field inside a long solenoid is given by the formula: \[B_{inside} = \mu_0 n I\] where \(\mu_0\) is the permeability of free space, \(n\) is the number of turns per unit length, and \(I\) is the current. Show more…

A long straight, solid metal wire of radius $2 \mathrm{~mm}$ carries a current uniformly distributed over its circular cross-section. The magnetic field induction at a distance $2 \mathrm{~mm}$ from its axis is $B$. Then, the magnetic field induction at distance $1 \mathrm{~mm}$ from axis will be (a) $B$ (b) $B_{1} 2$ (c) $2 \underline{B}$ (d) $B$
Magnetic Effect of Current
Round 1
An ideal solenoid ( $N_{1}$ turns, length $L_{1},$ radius $r_{1}$ ) is placed inside another ideal solenoid ( $N_{2}$ turns, length $L_{2}>L_{1}$, radius $r_{2}>r_{1}$ ) such that the axes of the two coincide. (a) What is the mutual inductance? (b) If the current in the outer solenoid is changing at a rate $\Delta I_{2} / \Delta t,$ what is the magnitude of the induced emf in the inner solenoid?
A long straight wire of radius "a" carries a steady current I the current is uniformly distributed across its cross-section. The ratio of the magnetic field at $\mathrm{a} / 2$ and $2 \mathrm{a}$ is (a) $(1 / 4)$ (b) 4 (c) 1 (d) $(1 / 2)$
