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
