Invisible Power - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
Is it strange that an invisible force can make a metal ring jump up? This is because there is a coil installed below the riser of the exhibition items, which generates a magnetic field when powered on. The metal ring attached to the iron pipe is subjected to the magnetic field generated by the coil, resulting in induced current. If this induced current is represented by a graph, it looks like a vortex in water, so we call it eddy current. Eddy currents also generate magnetic fields, which are opposite in direction to the coil's magnetic field and repel each other, causing the metal ring to overcome the Earth's attraction and jump high. So, the invisible magnetic field force lifted the small metal ring up. As is well known, electromagnets work by utilizing the magnetic effect of current. Electric motors and transformers are made by using electromagnetic induction phenomena, but not everyone knows that induction cookers use the principle of magnetic field induced eddy current heating. They use alternating current to generate an alternating magnetic field through coils. When the magnetic induction lines in the magnetic field reach the bottom of the iron containing pot, countless powerful small eddy currents are generated, causing the pot to quickly heat up on its own and then heat the food inside the pot.
