The force on a particle in a magnetic field is the idea behind electromagnetic pumping. It is used to pump metallic fluids (such as sodium) and to pump blood in artificial heart machines. The basic design is shown in Fig. 20- 48. An electric field is applied perpendicular to a blood vessel and to a magnetic field, explains how ions are caused to move. Do positive and negative ions feel a force in the same direction?
