일반물리학 2 — Magnetic Fields: Problem 29

29 A circular coil of 500 turns has a radius of 1.90 cm. (a) Calculate the current that results in a magnetic dipole moment of magnitude \(1.90 \text{ A} \cdot \text{m}^2\). (b) Find the maximum magnitude of the torque that the coil, carrying this current, can experience in a uniform 35.0 mT magnetic field.
