A diamagnetic current flowing across the magnetic field has been detected in a system of a rotating electron beam and a plasma. This current is caused by the rf pressure of a packet of cyclotron waves excited in the plasma. The current flow is accompanied by intense electromagnetic emission from the plasma and by the appearance of electrons with a large transverse energy.
