Homework Statement



A coil of wire has 600 turns and is 5.5 cm in diameter is in a magnetic field that decreases from 2.2 T to 0 T in 6.2 ms. The axis of the coil is parallel to the field. The coil is hooked up to two resistors of 120 Ω and 200 Ω connected in parallel. What is the maximum current through the 200 Ω resistor?

Homework Equations



B=uoNI/l
I=V/R
R= (1/R1+1/R2)-1
?

The Attempt at a Solution



I know I need to find voltage and then find current of just the 200 ohm resistor
