An electromagnetic pump or conveyor trough for generating a traveling magnetic field by means of current carried by conductors mounted in slots in the bottom of the trough to move an electrically conductive liquid wherein a first hollow tubular conductor having its bore eccentrically offset toward the bottom of the slot and a second hollow tubular conductor with a height which does not substantially exceed the electromagnetic penetration depth are mounted atop each other in each slot with the second conductor nearest the open end of the slot.
