Abstract

The invention discloses an electromagnet teaching experimental device, belonging to the field of teaching experimental aids. The electromagnet teaching experimental device comprises a hollow base, wherein a power supply is arranged in the base; two supporting plates are vertically arranged on the upper surface of the base; the two supporting plates are arranged at intervals; a plurality of connecting rods, which are horizontally arranged, are connected between the two supporting plates at intervals; coils are arranged on the surfaces of the connecting rods; each coil is arranged at one end ofthe corresponding connecting rod; and magnets are slidingly connected to the connecting rods. According to the electromagnet teaching experimental device, pins can be prevented from getting magnetizedin an electromagnet teaching experiment, so that influence to an experimental effect can be avoided.

Description

technical field [0001] The invention belongs to the field of teaching experiment equipment, and in particular relates to an electromagnet teaching experiment device. Background technique [0002] An electromagnet is a device that generates electromagnetism when energized. A conductive winding matching its power is wound on the outside of the iron core. This current-carrying coil is magnetic like a magnet, and it is also called an electromagnet (electromagnet). We usually make it into a bar or shoe shape to make the core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately when it is powered off, we often use soft iron or silicon steel materials that demagnetize faster. Such an electromagnet is magnetic when energized, and the magnetism disappears when the power is turned off. The electromagnet is widely used in our daily life, and the power of the generator has been greatly improved due to its invention. [0003] At present, in schools,...
