Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points A circular coil of 210 turns and area 0 . 24 m 2 is in a uniform magnetic field of 0 . 3 T. The maximum torque exerted on the coil by the field is 0 . 0017 N m. Calculate the current in the coil. Answer in units of A. 002 (part 2 of 2) 10.0 points Assume the 210 turns of wire are used to form a single-turn coil with the same shape but much larger area. What is the current if the maximum torque exerted on the coil by the field is 0 . 0017 N m? Answer in units of A. 003 10.0 points A circular loop of radius 3 . 85 cm contains 66 turns of tightly wound wire. If the current in the windings is 0 . 413 A and a constant magnetic field of 0 . 356 T makes an angle of 65 . 8 with a vector perpendicular with the loop, what torque acts on the loop?...
