Question A bar magnet when placed at an angle of \( 30^{\circ} \) to the direction of magnetic field induction of \( 5 \times 10^{-2} \mathrm{~T} \), experiences a moment of couple \( 25 \times 10^{-6} \mathrm{~N}-\mathrm{m} \). If the length of the magnet is \( 5 \mathrm{~cm} \) its pole strength is
(A) \( 2 \times 10^{-2} \mathrm{~A}-\mathrm{m} \)
(B) \( 5 \times 10^{-2} \mathrm{~A}-\mathrm{m} \)
(C) \( 2 \mathrm{~A}-\mathrm{m} \)
(D) \( 5 \mathrm{~A}-\mathrm{m} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
