153924 Two short bar magnets $A$ and $B$ are arranged coaxially. The distance between their centers is $\mathbf{3 0}$ cm. A compass needle placed on their axis at a distance of $6 \mathrm{~cm}$ from $B$ shows no deflection. The ratio of the magnetic moments of $A$ and $B$ is
153926 A moving coil galvanometer has a rectangular wire coil of enclosed area $0.001 \mathrm{~m}^{2}$ and 500 turns. The coil operates in a radial magnetic field of $0.2 \mathrm{~T}$ and carries a current of $6 \pi \times 10^{-8} \mathrm{~A}$. If the torsional spring constant is $6 \times 10^{-7} \mathrm{~N}-\mathrm{m} / \mathrm{rad}$, then the angular deflection of the coil in radians is
153928 A coil in the shape of an equilateral triangle of side $l$ is suspended between two pole pieces of a permanent magnet, such that magnetic field, $B$ is in plane of the coil. If due to a current $I$ in the triangle, a torque $\tau$ acts on it, the side $l$ of the triangle is -
