Usage - simulate the magnetic molecular structure of magnets and explain the phenomena of magnetization and demagnetization. Structure - cuboid fully transparent plastic box. - at the bottom are twenty-four steel sheets, arranged in four rows, six in each row. - 24 small magnetic plates are attached to the steel sheets, and each small magnetic plate can be wrapped. Operation and demonstration - Use a bar magnet to move the model in one direction. At this time, the small magnets are arranged regularly, and this arrangement does not change after the strip magnet has been removed. - Use hoof magnets to move irregularly across the flat glass (or vibrate the box accordingly) to disorder the small magnets. At this time, the magnetic forces of the small magnets cancel each other and the model is not displayed as a whole, but the demagnetization process is simulated. Key benefits - Provides a clear, visual demonstration of magnetization and demagnetization in a controlled, observable setup. - The initial regular arrangement remains stable after external motion, allowing repeatable demonstrations and step-by-step teaching. - The transparent cuboid box allows real-time observation of internal magnetic behavior while the bottom steel sheets and attached small magnets form a visible arrangement. - Simulates both alignment and disordering processes, enabling learners to see how magnetic domains respond to external fields and disturbances. Attributes and performance - Function: educational model for magnetism concepts including magnetization and demagnetization. - Compatibility: designed to be used with a bar magnet to induce directional arrangement and with hoof magnets to create irregular movement for demagnetization effects. - Size and form: cuboid transparent plastic box suitable for classroom desks or display. - Material: transparent plastic enclosure with steel sheets and small magnetic plates mounted underneath. - Behavior: arranged magnets stay in a regular pattern after initial alignment when moved by a bar magnet; irregular movement induces disorder and simulates demagnetization. Use scenarios - Classroom demonstration: teach students how external magnetic fields align magnetic domains and how disordering forces can reduce overall magnetization. - Science fair or project display: illustrate the concept of magnetic domains, magnetization, and demagnetization with a hands-on model. - Teaching lab or tutor sessions: provide a repeatable setup to compare the effects of directional versus irregular magnetic influence on magnetized materials.
