Uniform magnetic field B points out of the page, and lies within a circle of radius R = 4.18 m. An electron is placed at the top edge of the circle (at distance R above the center of the circle). If the magnitude of the dB magnetic field begins to decrease at a steady rate = -6.71 T/s, find the force felt by the electron, in N. dt The sign of the answer gives the direction of the force: positive to the right, negative to the left.
