Charged particles propagating in an inhomogeneous large amplitude microwave field experience a nonlinear force called the ponderomotive force. This effect can be theoretically evaluated either from the single particle or the fluid theories. For magnetized particles, these two descriptions predict quite different behaviors. A previous experiment [J. Vaclavik {ital et} {ital al}., Phys. Fluids {bold 29}, 2034 (1986)] has shown results in agreement with the fluid theory. Here, an experiment with a magnetized electron beam is described, which brings out a ponderomotive deflection in agreement with the single particle theory. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
