Magnetohydrodynamic ( MHD ) theory predicts that the motion of a conducting fluid ( e . g . the interplanetary medium ) in a magnetic field, induces electric currents which in turn generates magnetic fields, and in this respect it behaves like a MHD dynamo.

In 1966 he was the first to demonstrate and describe the process of'flux expulsion'by which a conducting fluid undergoing rotating motion acts to expel the magnetic flux from the region of motion, a process now known to occur in the photosphere of the Sun and other stars.
