This 6-coil Ring Accelerator features a transparent acrylic structure and 940nm infrared triggering system, driving a high-magnetic steel ball continuously along a 23cm circular track to vividly demonstrate electromagnetic induction and energy conversion—an ideal teaching aid for physics classrooms, science museums, and innovative lab experiments. Each coil is independently controlled by a circuit board and is not affected by each other. This accelerator incorporates 940nm infrared transmitter-receiver pairs as trigger sensors, driving a 15mm high-magnetic steel ball continuously along a 23cm transparent circular track at approximately 20-30 laps per minute. The six coils are sequentially energized to generate an alternating magnetic field, propelling the steel ball in continuous circular acceleration—vividly demonstrating the complete physical process of electromagnetic induction, magnetic field propulsion, and energy conversi Open track, easy to start, just a hand to drive, and intuitive and convenient to demonstrate the principle. Infrared sensor, special circuit, long life, high accuracy, almost no delay.
