Abstract
The invention discloses an adjusting method of an electromagnet driven rotating fluid self-variable resistor capable of being applied to an electronic or electric system. The resistor is mainly composed of a cavity, conductive fluid, a magnetic field, an electrode, and a resistor body. The conductive fluid is filled in the cavity. The volume of the conductive fluid is smaller than the effective volume of the cavity. The electrode is arranged in the center of the cavity and contacts with the conductive fluid. The resistor body is arranged in the cavity. Part of the resistor body contacts with the conductive fluid. Part of the resistor body is exposed in the residual space of the cavity. The electrode and the resistor body form an electrical loop through the conductive fluid. The magnetic field has a component in a vertical direction of the surface of conductive fluid between the electrode and the resistor body. The structure is simple, the resistor is difficult to break and is durable, and the cost is low.
