Around flat metal coil has 180 turns and negligible resistance. it is connected in a series circuit with a 17-ω resistor, with nothing else in the circuit. you measure that a 6.0-a current flows through the resistor when a magnetic field through the coil, perpendicular to its area, is changing at 3.0 t/s. what is the radius of the coil?
(a) 0.043 m
(b) 0.014 m
(c) 0.25 m
