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 equal to \[4\pi \times {{10}^{-3}}\]Tesla. It makes an angle of 30o with the direction of magnetic induction. The value of the torque acting on the magnet is [MP PMT 1993]

• A.            \[2\pi \times {{10}^{-7}}N\times m\]                            
• B.            \[2\pi \times {{10}^{-5}}N\times m\]
• C.            \[0.5N\times m\]               
• D.            \[0.5\times {{10}^{2}}N\times m\] (\[{{\mu }_{0}}=4\pi \times {{10}^{-7}}weber/amp\times m\])
