Application of automatic control in physical experiment devices

Abstract

The invention relates to application of automatic control in physical experiment devices. The application is formed by an operation panel, an aluminum rack, an iron core, an electromagnet, guide rails and an electrified conductor. The aluminum rack is used for fixing the electromagnet and the iron core. The electromagnet and the iron core are used for generating magnet field and are fixedly installed in the aluminum rack. The guide rails are installed on two sides of the aluminum rack and are used for serving as wires of the electrified conductor and supporting the electrified conductor in the middle of the magnet field. The application is characterized in that the electrified conductor is arranged on the guide rails and can move affected by ampere force; an experiment device switch, two ampere meters, a timer, an experiment starting button, a current size toggle switch, a magnet field strength toggle switch, a current direction toggle switch, a magnetic field direction toggle switch and a magnetic field width toggle switch are arranged on the operation panel. According to the invention, direction and strength of magnetic field can be effectively changed; size of current passing through the electrified conductor and effective length for accessing the magnetic field can be also changed; and it is easy for students to study and judge direction and size of the ampere force.

Description

technical field [0001] The invention relates to an experiment control device, in particular to the application of an ampere force experiment control device in physical experiment equipment. Background technique [0002] A long wooden board, a pulley, a trolley, and a ticking timer constitute experimental equipment that is widely used and frequently used in physical experiments. But there are also some unsatisfactory aspects. For example, in the experiment, the car would rush out of the long plank and roll on the ground, and the timer would do some useless work. At the end of the experiment, the operator had to block the car while turning off the timer, which was easy cause confusion. In order to solve these problems and bring convenience to the experiment, I introduce automatic control into the experiment. Contents of the invention [0003] In order to change the problems existing in the traditional ampere force experimental control device and improve the experimental ef...
