This letter discusses how current loops are established in the plasma atmosphere of a pulsar when the rotational and magnetic axes are aligned. A model is outlined in which the rotation of a pulsar about its dipole magnetic-field axis induces an electric field that draws electrons primarily from the polar regions, giving rise to a stellar charge. Regions are delineated in which the plasma flow is dominated by either the electric or magnetic field, and three groups of magnetic surfaces are identified. The model predicts that electrons which flow out along a magnetic surface where the stellar surface angle is less than a certain inner polar angle will enter the electric-dominated flow region, cross to a magnetic surface with a larger stellar surface angle, and follow this new surface back to the star, thus forming the required current loop. It is noted that this current loop does not extend to the pulsar's nebula and does not represent any particle loss from the star. The validity of the present results is discussed.-
