Problems solved by technology

[0003] After knowing the direction of the current and the direction of the magnetic field line, the direction of the Ampere force can be judged by the left-hand rule. In the teaching process, there is no related Ampere force demonstration teaching aid. When learning the Ampere force, beginners cannot intuitively observe the Ampere force. The effect produced, and the interest in learning is not high

Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] see figure 1 , a simple ampere force demonstrator, including a magnet 100, the magnet is in the shape of a horizontal "U", a horizontal track 200 is arranged in the opening 110 of the magnet, and a hollow aluminum tube that can move along the horizontal track is arranged on the horizontal track 200 300. The hollow aluminum tube 300 is connected to the DC power supply 500 through the switch 400.

[0014] Manufacture of the magnet: select two square planks of 40cm*18cm*2.5cm, use a woodworking drill with a diameter of 25mm, and drill holes on the square planks. A thick iron plate is fixed on one side of the plank, and a strong magnet is placed in the hole of the square plank. Such a piece is used as the N pole of the magnet, and one piece...

Abstract

The invention discloses a simple and easy ampere force demonstrator, which comprises a magnet, wherein the magnet is in a horizontal U shape; a horizontal rail is arranged in an opening of the magnet; and a hollow aluminum pipe capable of moving along the horizontal rail is arranged on the horizontal rail, and is connected with a direct current power supply through a switch. The simple and easy ampere force demonstrator has the characteristics of simple structure and convenience for manufacturing. When used in teaching, the simple and easy ampere force demonstrator can intuitively demonstrate an effect generated by ampere force, can increase the learning interest of students, and plays an active role in learning.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to an ampere force demonstrator. Background technique [0002] The force of the magnetic field on the current is usually called the Ampere's force, and the direction of the Ampere's force is determined by the left-hand rule. The left-hand rule refers to: put the left hand flat, make the thumb perpendicular to the other four fingers, and all of them are in the same plane as the palm; then put the left hand into the magnetic field, let the magnetic induction line pass through the palm vertically, and the four fingers point to the direction of the current , then the direction of the thumb is the direction of the force on the conductor. [0003] After knowing the direction of the current and the direction of the magnetic field line, the direction of the Ampere force can be judged by the left-hand rule. In the teaching process, there is no related Ampere force demonstration teaching aid. Wh...
