Abstract
The theory of hydromagnetic flow through a straight channel in the presence of a uniform applied external magnetic field transverse to the direction of flow is discussed. Examples are worked for the cases of circular, elliptic, and rectangular cross sections. Experiments were performed with such ducts. In the circular and elliptical cases the potential induced across the duct was measured as a function of angle with respect to the applied field. Rectangular ducts were investigated by means of pressure gradient measurements. All results were in good accord with theory except for an aluminum rectangular duct which acted as if it were actually nonconducting, presumably due to an insulating surface layer.
