Embodiment Construction

[0017] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to teaching equipment for verifying the Lenz's law. The teaching equipment for verifying the Lenz's law comprises a base, a first insulating tube, a plurality of verifying coils,a plurality of light-emitting elements and a magnetic part, wherein the first insulating tube is arranged on the base, the plurality of the verifying coils are all wound around the first insulating tube and spaced apart one another, the plurality of the light-emitting elements are respectively connected to the plurality of the verifying coils, each of the light-emitting elements and the corresponding verifying coil form a closed loop, the magnetic part is used for being placed in the first insulating tube, and declines under the action of gravity, and the plurality of the verifying coils sequentially generate induced currents to drive the plurality of the light-emitting elements to emit light sequentially. The teaching equipment for verifying the Lenz's law is intuitive and easy to teach.

Description

technical field [0001] The invention relates to a teaching device for verifying Lenz's law. Background technique [0002] Lenz's law is a law of electromagnetism, which can be used to judge the direction of electromotive force generated by electromagnetic induction. In Lenz's law, the induced current has such a direction that the magnetic field of the induced current always hinders the change of the magnetic flux causing the induced current. Lenz's law can also be expressed as: The effect of the induced current always opposes the cause of the induced current. In the teaching of electronics and electrical engineering, it is often necessary to teach Lenz's law to students. However, there is currently no intuitive object to verify to assist students in understanding, which makes the teaching not very intuitive. Contents of the invention [0003] Based on this, it is necessary to provide a more intuitive teaching equipment for verifying Lenz's law. [0004] A teaching devic...
