Problem 4 AB = 0.1 [T/s] At A spatially uniform magnetic field increases in time at the rate of AB/At = 0.1 [T/s]. It pierces a conducting loop with an area A = 10-2 2 [m]. a) Draw the direction of the induced current and the induced magnetic field. b) Calculate the induced potential. c) If the loop has a resistance R = 1 [], find the induced current.
