Asked by J
A coil of wire with 200 circular turns of radius of 3 cm is in a uniform magnetic field along the axis of the coil. the coil has R=40 ohms. At what rate, in Teslas per second, must the magnetic field be changing to induce a current of .150 A in the coil?
I don't know if I am using the wrong equation or what, but I can't get the right answer for this one

V = A N dB/dt
N is the number of turns and A is the coil area.
V = I R = 6 Volts
Solve for the rate of change of B, dB/dt
