Jumping Ring - Customized Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Operating instructions: Press the operating button and carefully observe the movement and changes of the metal ring. Scientific principle: When alternating current passes through a coil, the coil generates an alternating magnetic field, and the metal aluminum ring generates reverse eddy currents and corresponding magnetic fields. The polarity of the two magnetic fields is opposite, generating repulsive forces and causing the metal aluminum ring to jump up. Think about it, can a metal aluminum ring be suspended using direct current? The exhibition items vividly demonstrate Lenz's law to the audience by inducing a magnetic field through an energized coil, causing the aluminum ring to jump. This exhibition items consist of a table body, silicon steel columns, transparent acrylic covers, aluminum rings, etc. A silicon steel column is erected on the platform, and the coil is wound around the lower part of the silicon steel sheet column, with an aluminum ring wrapped around the silicon steel sheet column. When powered on, the coil generates a magnetic field. As the aluminum ring acts as a closed circuit, it induces current and forms a magnetic field. At this time, the magnetic field is opposite to that of the aluminum ring, so the strong force causes the aluminum ring to jump up.
