32.29. Model: A magnetic field exerts a force on a moving charge. Visualize: Please refer to Figure Ex32.29. Solve: (a) The force on a charge moving in a magnetic field is r r r Fon q = qv × B = (qvBsinα, direction of right-hand rule) The direction of the force on a negative charge is opposite the direction determined by the right-hand rule. Since r the force F is out ofr the page and the velocity of the negative charge is to the left and up in the plane of the paper, the magnetic field B must be in the plane of the page, 45° clockwise from straight up. (b) The magnetic field on the positive charge is in the plane of the page, 45° counterclockwise from straight down.
