... = 0.225 A I= R 12.5 Ω (b) Once the loop is entirely inside the magnetic field, there is no change in flux. If there is no flux, there is no induced magnetic field and therefore no current, so I = 0. (c) As the loop leaves the field, the flux points out of the page but is decreasing. To balance this, ...
