A single-turn plane loop of wire with a cross-sectional area 200 cm2 is perpendicular to a magnetic field that increases uniformly from 0.200 T to 2.800 T in 2.20 seconds. What is the magnitude of the induced current if the resistance of the coil is 8.00 Ω?

Hi,

    Induced current I = e/R
                             = (dB/dt)A/R
                              = [(2.8T -0.2T)/(2.2s)](200*10-4m2)/(8Ω)
                             = 2.95mA

Hope this help you.
