Abstract It is shown that a pulsar surrounded by a corotating magnetosphere region can possess a net charge. If there is no streaming, the star must be charged. The result is shown for the special relativistic case as well as for the fully general-relativistic model, including the effects of strong gravitation and the dragging of inertial frames. The value of the charge is of the order of 10$sup 12$ coulombs and depends upon the angle between the rotation and magnetic dipole axes. In the special relativistic case, the dipole magnetosphere contains no net charge, whereas when general relativity is included, the magnetosphere possesses net charge which can be comparable to that of the star itself. This is a new general-relativisitc effect. Because of their net charge, pulsars possessing this type of corotating magnetosphere region are sources of charged particles. (AIP)
