Electromagnetic control slide rheostat

Abstract

The invention discloses a slide rheostat, in particular an electromagnetic control slide rheostat. The electromagnetic control slide rheostat comprises the slide rheostat, a coil, a sliding rod and a sliding sheet, wherein the coil, the sliding rod and the sliding sheet are arranged on the slide rheostat. The electromagnetic control slide rheostat is characterized in that both ends of the sliding rod are respectively provided with electromagnetic control devices; the electromagnetic control devices are connected with a variable frequency power source through leads, and each electromagnetic control device comprises an electromagnet and a transformer which are connected. The electromagnetic control slide rheostat has simple structure and convenient use and can remotely control the sliding of the sliding sheet of the slide rheostat by changing voltage during a physics experiment, thereby regulating the resistance of the slide rheostat connected into a circuit, realizing the automation of electrical elements and bringing the convenience for the experiment.

Description

(1) Technical field [0001] The invention relates to a sliding rheostat, in particular to an electromagnetically controlled sliding rheostat. (2) Background technology [0002] In the learning experiment of physical electricity, the sliding rheostat is a commonly used electrical component.
