Lazy Ring
Exhibit Dimensions: Transport dimensions: 540×440×640mm, Display dimensions: 540×440×1450mm. Exhibit Composition: Consists of an ABS plastic molded box, ABS plastic molded base, ABS milky white plastic molded operation tabletop with color silk-screened flip instruction board, acrylic tube, magnets, aluminum rings, etc. Observe the speed changes of the aluminum ring in the acrylic tube. Explore Lenz's Law. That is, when a closed conductor and a magnet undergo motion that cuts magnetic field lines, due to the change in magnetic flux passing through the closed conductor, an induced current is generated in the closed conductor, and this current will hinder the relative motion between the two, simply put, the rule of 'reject when approaching, retain when leaving'. The closed aluminum ring is a conductor; when passing through the sliding column, an induced current is generated, which hinders the downward motion of the aluminum ring, so its falling speed is the slowest; although the hollow aluminum ring is also a conductor, the current generated by the hollow aluminum ring is smaller compared to the closed aluminum ring, so the resistance is smaller, and thus its falling speed is faster; the plastic ring is not a conductor, so it is not affected by the magnetic field when passing through the tube, and undergoes free fall, with the fastest falling speed.
