Abstract

The invention relates to the technical field of physics teaching, in particular to a physics teaching experiment device based on electromagnetic induction, which comprises a teaching table, a first motor is mounted on one side in the teaching table through bolts, a gear is welded to the end part of the first motor, a limiting frame is fixedly mounted in the teaching table, and a movable column is movably arranged in the limiting frame. An outer gear ring is welded to the outer wall of the movable column, rotating discs are welded to the two ends of the movable column, a stretching rod is movably connected to one side of the outer wall of each rotating disc, a displacement block is movably connected to the bottom end of each stretching rod, an induction outer frame is installed outside each displacement block through a bolt, and an induction frame is installed outside each induction outer frame through a bolt. After the gear is driven by the first motor, the rotary disc moves, the induction outer frame and the induction frame are moved through the stretching rod, electromagnetic induction is generated around the displacement magnetic bar by the electromagnetic coil outside the displacement magnetic bar, and electromagnetic induction observation and experiment are facilitated.

Description

technical field [0001] The invention relates to the technical field of physics teaching, in particular to a physics teaching experiment device based on electromagnetic induction. Background technique [0002] The phenomenon of electromagnetic induction means that a conductor placed in a changing magnetic flux will generate an electromotive force. This electromotive force is called an induced electromotive force or an induced electromotive force. If the conductor is closed into a loop, the electromotive force will drive the electrons to flow, forming an induced current. Magnetic induction refers to the phenomenon of induced electromotive force due to changes in magnetic flux. [0003] Chinese Patent No. CN209168500U provides an electromagnetic induction demonstration experimental device for physics teaching, including a demonstration frame and an electromagnetic induction mechanism arranged on the demonstration frame; the electromagnetic induction mechanism includes a permane...
