Embodiment Construction

[0020] 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.

[0021] 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 a demonstration device of the left-hand rule and the right-hand rule. The demonstration device of the left-hand rule and the right-hand rule includes a base, a transmission component, a magnetic pole rotating component and at least one wire component; the transmission component includes a handle and a gear transmission structure; the gear transmission structure is connected to the handle; the magnetic pole rotating component includes a rotating disk and two magnetic strips; the rotating disk is connected to the gear transmission structure; the two magnetic strips are detachably inserted on the rotating disk; the two magnetic strips are arranged symmetrically; and the magnetic poles on the surfaces of the two magnetic strips facing each other are different. The demonstration device of the left-hand rule and the right-hand rule is convenient for teaching.

Description

technical field [0001] The invention relates to a demonstration device for the left-hand rule and the right-hand rule. Background technique [0002] In electromagnetic teaching, it is often necessary to teach the left-hand rule and the right-hand rule, and sometimes it is necessary to explain dynamic balance to understand dynamic balance. Judgment principle of the right-hand rule: Stretch the right hand to let the magnetic induction line enter from the palm of the hand, and make the thumb point to the direction of the wire movement. At this time, the direction pointed by the four fingers is the direction of the induced current. The judging principle of the left-hand rule is: stretch out the left hand to let the magnetic induction line enter from the palm of the hand, and make the four fingers point to the direction of the current. At this time, the direction pointed by the thumb is the direction in which the wire moves. However, these left-hand rules, right-hand rules and d...
