Magnetic field visualization

This exhibit uses a display screen to allow visitors to intuitively see the direction of magnetic field lines, observe the phenomenon of the intersection of magnetic field lines between two magnets, and then think about the distribution characteristics of magnetic field lines. The exhibit consists of LCD TVs, magnets, rotating mechanisms, cameras, and dancing paper clip components. When visitors rotates the bar magnet or presses the button in front of the dancing paper clip, the camera captures the motion and displays it synchronously on the screen. At the same time, media animations simulate the distribution of magnetic force lines around the magnet to assist visitors in understanding relevant knowledge. one Step into the exhibit, manually rotate the bar magnet or press the button in front of the dancing paper clip to watch the LCD TV screen and observe the direction and distribution of magnetic field lines Through multimedia videos played on the screen, learn about scientific knowledge related to magnetic poles and magnetic lines. Presentation principle: The camera captures visitors' movements of rotating magnets and pressing buttons, transmits the action signals to the system, and the system drives the media animation to synchronously simulate the circumference of the magnet in the corresponding state.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
