Magnetic Rhythm

The exhibit the relationship between the attraction of a magnet and the distance of the attracted object through a simple interactive device, revealing the physics knowledge of magnetic field strength.

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.

The exhibit design features a four cornered stand with a narrow top and wide bottom, and a triangular side profile. Above the shelf is an iron rod parallel to the ground, with 21 iron rods hanging at equal intervals perpendicular to the ground. Below the iron rods are disks embedded with magnetic steel. Reasonable layout, convenient for sufficient space above to swing back and forth. In addition, there are cranks above the first, eleventh, and twenty-first iron bars for tourists to hold. By moving any one of the cranks, the corresponding pendulum can be controlled to swing back and forth, and the surrounding pendulum will be affected by magnetic force, attracting each other and swinging together with the nearby pendulum. The swing angle of a magnet pendulum is influenced by the magnitude of the magnetic force and the initial swing amplitude. As the number of individual swings increases, the swing amplitude gradually decreases, forming a snake like swimming state.
