1. The problem statement, all variables and given/known data A circular coil of 720 turns and area 0.6 m^2 is in a uniform magnetic field of 0.63 T. The maximum torque exerted on the coil by the field is 0.0026 N · m. a) Calculate the current in the coil. b) Assume the 720 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 0.0026 N · m? NOTE: Sigfigs do not matter 2. Relevant equations T = IABn 3. The attempt at a solution Part A: I solved by substitution using the equation T = IABn, getting T = 9.5532e-6 N · m (answer is correct) Part B: This is the part I'm having trouble with. I thought I could fine the new Area doing the following (I'm sure this approach is wrong): .6 = pi*r^2, r*720 = 314.7 A = pi*314.7^2, plugging in the new area into T = IAB gives the wrong answer. I'd be very grateful for any help.
