Illustrating Phenomena Such As Magnetization and Demagnetization Magnetic Molecular Model Physics Physics Teaching Equipment Magnetic Molecular Structure of A Magnet

Use:Simulate the magnetic molecular structure of a magnet and explain the phenomena of magnetization and demagnetization.Structure:It has a rectangular parallelepiped shape and a fully transparent plastic box. Twenty-four steel s are placed in the bottom bottom, arranged in four rows, six in each row. Twenty-four small magnetic s are placed on the steel s, and each small magnetic can be freely wound around the steel . Rotate.Instructions:1. Use a bar magnet to move in one direction on the model. At this time, the small magnetic s are arranged regularly, and this arrangement will not change after the strip magnet is removed. In this way, one end of the model becomes the S pole and the other end becomes the N pole, simulating the magnetization process.2. Use hoof magnets to move irregularly above the flat glass (or vibrate the box appropriately) to make the small magnetic s arranged in disorder. At this time, the magnetic forces of the small magnetic s cancel each other out, and the model is not displayed as a whole, and the demagnetization process is simulated.Maintenance:1. It should be handled with care to avoid damaging the tip.2. Store in a dry place, no corrosive gas, liquid and away from strong magnetic field.

• Usage: Simulate the magnetic molecular structure of magnets, explain the phenomena of magnetization and demagnetization.
• Structure: Cuboid shape, fully transparent plastic box. Twenty-four steel s are placed at the bottom, arranged in four rows, six in each row. Twenty-four small magnetic plates are placed on the steel s, and each small magnetic can be wound.
