Novel measurement experiment instrument for internal magnetic field distribution of multifunctional solenoid

Abstract

The invention relates to a novel measurement experiment instrument for internal magnetic field distribution of a multifunctional solenoid. The measurement experiment instrument comprises a three-coilsolenoid forward-and-reverse connection board, a Hall plate current power supply line forward-and-reverse connection board, a three-coil solenoid connection switch connection board, a three-coil solenoid current power supply line, a Hall plate current power supply line, a Hall plate fixing copper tube, a three-coil solenoid, a solenoid and Hall plate fixing copper tube support base slide, and an electric cabinet. Three coils of the three-coil solenoid include an inner coil, a middle coil and an outer coil. Each coil guides out two guide lines. The inner coil guides out a three-coil public lineand an inner coil guide line, the middle coil guides out the three-coil public line and an middle coil guide line, and the outer coil guides out the three-coil public line and an outer coil guide line. The measurement experiment instrument has the advantages of novelty in overall structure design thinking, solution feasibility, and standard and reasonable structural layout.

Description

technical field [0001] The invention relates to an experiment instrument, in particular to a novel multifunctional solenoid internal magnetic field distribution measurement experiment instrument. Background technique [0002] Solenoid magnetic field distribution measurement is an important experimental project in the Department of Physics and Electricity of the University. The solenoid magnetic field distribution is not only related to the number of coil turns, but also related to the magnitude of the current passing through the coil wire. At present, the experiment of measuring the solenoid magnetic field distribution Although there are some experimental instruments and devices in the market and physical laboratories, these experimental instruments all have some defects: (1) the solenoid used in the experiment has no fixing device; (2) it is difficult for the experimenter to accurately place the Hall sensor on the coil. The central position and the movement in the direction...
