DIY Electromagnetic Swing STEM Kit - Kids Wooden Toys Science Experiment Technology Electromagnetic Swing STEM Educational Puzzle STEM (Note that the coil isExperimental principle: The principle of electromagnetic swing: After the wire is energized, a magnetic field will be generated around the wire. If the wire is wound into a coil, this magnetism will be increased. In this experiment, the copper wire has a layer of insulating film, which produces magnetism after being wound into a coil and energized. The more turns of the coil, the stronger the magnetism. The coil interacts with the permanent magnet
