Problems solved by technology

At present, the experimental devices for exploring the Ampere force on the market use the uniform magnetic field generated by permanent magnets. Generally, the strength and direction of the magnetic field cannot be effectively changed during the experiment. If you want to change the strength of the magnetic field and the direction of the magnetic field, you can use permanent magnets. In addition, in this type of experimental device, the judgment of the magnitude of the Ampere force can only be made by eye observation and rough comparison, and the experimental phenomenon is not intuitive enough.

Abstract

The invention relates to an ampere force experimental control device which is composed of an operation panel, an aluminum frame, an iron core, two electromagnets, a guide rail and an electrified conductor. Compared with a traditional ampere force experimental control device, the ampere force experimental control device can effectively change the direction and intensity of a magnetic field, change the magnitude and direction of a current flowing through the electrified conductor and the effective length of the access magnetic field, and automatic control, counting and the like further can be conducted on an experiment, students can conveniently research the direction and magnitude of ampere force according to the device, and the experiment effect is improved.

Description

technical field [0001] The invention relates to an experiment control device, in particular to an ampere force experiment control device. Background technique [0002] In the high school physics Ampere force experiment, the magnitude of Ampere force is related to the strength of the magnetic field, the magnitude of the current in the current-carrying conductor and the length of the conductor in the magnetic field, and the direction of the Ampere force is related to the direction of the magnetic field and the direction of the current in the current-carrying conductor. At present, the experimental devices for exploring the Ampere force on the market use the uniform magnetic field generated by permanent magnets. Generally, the strength and direction of the magnetic field cannot be effectively changed during the experiment. If you want to change the strength of the magnetic field and the direction of the magnetic field, you can use permanent magnets. In addition, in this type of...
