A round flat metal coil has 360 turns and negligible resistance. It is connected in a series circuit with 17 ohm resistor, with nothing else in the circuit. You measure that a 6 A current flows through the resistor when a magnetic field through the coil, perpendicular to its area, is changing at 3 T/s What is the radius of the coil
