Two long straight wires $P$ and $Q$ carrying equal current $10 \mathrm{~A}$ each were kept parallel to each other at $5 \mathrm{~cm}$ distance. Magnitude of magnetic force experienced by $10 \mathrm{~cm}$ length of wire $p$ is
$F_{1}$. If distance between wires is halved and currents on them are doubled, force $F_{2}$ on 10 cm length of wire $P$ will be:

A single current carrying loop of wire carrying current $I$ flowing in anticlockwise direction seen from +ve $z$ direction and lying in xy plane is shown in figure. The plot of $\hat{\mathbf{j}}$ component of magnetic field $\left(B_{y}\right)$ at a distance ' $a$ ' (less than radius of the coil ) and on $y z$ plane vs z coordinate looks like

As shown in the figure, a long straight conductor with semi-circular arc of radius $\frac{\pi}{10} \mathrm{~m}$ is carrying current $\mathrm{I}=3 \mathrm{~A}$, The magnitude of the magnetic field at the center $O$ of the arc is:
(The permeability of the vacuum $=4 \pi \times 10^{-7}$ $\mathrm{NA}^{-2}$ )
