Simulates Magnetic Molecular Structure Model Can Be Projected Simulates Magnetization and Demagnetization Phenomenon 24 Magnetic Needles

Specification:Size: 150*103*20mmMaterial: plastic box, magnetic needleWeight: about 105g netPurpose: It is used to simulate the magnetic molecular structure of magnets, and to illustrate phenomena such as magnetization and demagnetization.

• * Magnetic Molecular Model: Simulate the magnetic molecular structure of a magnet, illustrating phenomena such as magnetization and demagnetization.
• * Product Structure: cuboid in shape, fully transparent plastic box, 24 steel needles are placed on the bottom, arranged in four rows, six in each row, twenty-four small magnetic needles are placed on the steel needles, and each small magnetic needle can be wound around the steel needle rotation.
• * Use a bar magnet to move in one direction on the model. At this time, the small magnetic needles are regularly arranged. After the bar magnet is removed, the arrangement will not change. In this way, one end of the model becomes the S pole and the other end becomes the N pole, simulating the magnetization process.
• * Use a hoof-shaped magnet to move randomly above the flat glass (or properly vibrate the box) to make the small magnetic needles chaotically arranged. At this time, the magnetic forces of the small magnetic needles cancel each other out, and the model does not display as a whole, simulating the demagnetization process.
• * Practical Science: Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life
