153183 An electric current ' $I$ ' enters and leaves a uniform circular wire of radius $r$ through diametrically opposite points. A particle carrying a charge $q$ moves along the axis of the circular wire with speed $v$. What is the magnetic force experienced by the particle when it passes through the centre of the circle?

A very long wire carrying a current $4 \sqrt{2} \mathrm{~A}$ is bent at a right angles. The magnitude of magnetic field $(|\mathrm{B}|)$ at a point $P$ lying on a line perpendicular to the bent wire at a distance, $d$ $=20 \mathrm{~cm}$ from the point of the bending will be (Let $\mu_{0}=4 \pi \times 10^{-7} \mathrm{H} / \mathrm{m}$ )
153185 The magnetic field normal to the plane of a coil of $\mathbf{N}$ turns and radius $\mathbf{r}$ which carries a current $i$ is measured on the axis of the coil at a distance $h$ from the centre of the coil. This is smaller than the field at the centre by the fraction,
