The present study of Grad-Shafranov solutions for the ideal MHD flows around a magnetized rotating neutron star whose axes of rotation and magnetism are identical notes the force-free limit of this equation to be identical to the pulsar equation derived from a variational principle which minimizes the electromagnetic field energy within the constraints of fixed total angular momentum and total magnetic helicity. The pulsar equation is found to be a peacewise linear pdf with a class of solutions encompassing self-collimated electromagnetic jets along the star's rotation axis. 37 refs.
