1. A non-uniform magnetic field points out of the page as shown below in the figure. The increases at a constant rate of 2.0 mT as you move to the right. A square wire loop of 15 cm on a side lies on a plane perpendicular to field, and a 2.5 A current circles loop the counter-clockwise direction. Calculate the magnitude and direction of the net magnetic force on loop.
