A coil 2.0 cm in diameter has 300 turns. If the coil carries a current of 10 mA and lies in a magnetic field 5×10−2 T5 \times 10^{-2} \mathrm{~T}, the maximum torque experienced by the coil is

Options

  1. A4.7×10−2 N−m4.7 \times 10^{-2} \mathrm{~N}-\mathrm{m}
  2. B4.7×10−4 N−m4.7 \times 10^{-4} \mathrm{~N}-\mathrm{m}
  3. C4.7×10−5 N−m4.7 \times 10^{-5} \mathrm{~N}-\mathrm{m}
  4. D4.7×10−8 N−m4.7 \times 10^{-8} \mathrm{~N}-\mathrm{m}
