153150 A thin charged rod is bent into the shape of a small circle of radius $R$ the charge per unit length of the rod being $\lambda$. The circle is rotated about its axis with a time period $T$ and it is found that the magnetic field at a distance ' $d$ ' away $(d>R)$ from the center and on the axis, varies as $\frac{R^{m}}{d^{n}}$ The values of $m$ and $n$ respectively are

Consider two infinitely long wires parallel to $\mathrm{Z}$ axis carrying same current $I$ in the positive $Z$ direction. One wire passes through the point $L$ at coordinates $(-1,+1)$ and the other wire passes through the point $M$ at coordinates $(-1$, $-1)$. The resultant magnetic field at the origin $O$ will be
153152 Two concentric coplanar circular loops of radii $r_{1}$ and $r_{2}$ carry currents $i_{1}$ and $i_{2}$ respectively in opposite directions ( $i_{1}$ clockwise and $i_{2}$ anticlockwise). The magnetic induction at the centre of the loops is half of that due to $i_{1}$ alone at the centre. If $r_{2}=\mathbf{2} r_{1}$, the value of $i_{2} / i_{1}=$
