PURPOSE: To enhance power efficiency and reduce the cost of equipments and improve working property, by arranging the required number of coil units at the lower section in the main unit of the electromagnetic pump of dipping type, and by obtaining a portion containing no coil units, at the upper section.

CONSTITUTION: An induction core 5 has concave grooves 5a in quantity required for the suction of molten metal, at the lower section, and the concave grooves 5a are provided with coil units 6. In the meantime, the upper section of the induction core 5 is set to be a portion containing no coil units. Molten metal R conducted through the leading-in port 8a of the molten metal to a ring-formed passage S is advanced to the inlet 11 of the metal with action in the shifting field due to the coil units 6.
