An electromagnetic pump has a supply section and a magnetic force pumping
section wherein flow of a electrically conductive material through the
supply section is opposite to the flow of the material in the magnetic
force pumping section in some examples. Multiple coils surround the
supply and magnetic force pumping sections. Current flowing through the
multiple coils creates magnetic fields that magnetically couple with a
magnetic material disposed between the supply and magnetic force pumping
sections so that the fields penetrate the electrically conductive
material in the magnetic force pumping section substantially
perpendicular to the desired flow direction which maximizes the
magnitudes of magnetic forces applied to the electrically conductive
material.
