• A thin rectangular magnet suspended freely has a period of oscillation equal to $T$. Now it is broken into two equal halves (each having half of the original length) and one piece is made to oscillate freely in the same field. If its period of oscillation is $T'$, then ratio $\frac{{T'}}{T}$is

• A bar magnet of length 10 cm and having the pole strength equal to $10^{–3}$ weber is kept in a magnetic field having magnetic induction (B) equal to $4\pi \times {10^{ - 3}}$ Tesla. It makes an angle of $30^o$ with the direction of magnetic induction. The value of the torque acting on the magnet is (${\mu _0} = 4\pi \times {10^{ - 7}}weber/amp \times m$)
