The simplest case occurs when a charged particle Q moves perpendicular to a uniform field B with a Velocity V.
The magnetic force is perpendicular to the direction of displacement, a charged particle following a curved path in a magnetic field. The particle continues to follow this curved path until it forms a complete circle. The kinetic energy and velocity of the particle therefore remain constant. The direction of movement is affected, but not speed.

In the second part of the experiment it is observed that there is a central electrode surrounded by another electrode in the form of a ring, so that the particles that form the electric current move in a radial path. In the center of the container is a metallic steel cylinder.
A stack of magnets form a powerful magnetic field that surrounds the electrical currents generated between the electrodes. When current flows through the two electrodes, it generates a strong magnetic field that supports the system. This favorable condition causes the conductive liquid to rotate,
Direct current is created and controlled by an inverter. The rotation speed of the liquid depends on the voltage supplied.
The system does not work on alternating current.
