Electromagnetic acceleration principle: This is the same as the principle of an electromagnetic gun. A sensing coil is placed in the wire circle. When the sensor senses a small ball approaching the wire circle, the wire circle is instantly energized. The steel ball is attracted through the wire circle. After passing through the wire circle, the wire circle is instantly de-energized. The iron ball rolls downward in a straight line due to inertia. The circle then resumes cyclic acceleration. The speed becomes faster and faster, the circles accelerate more and more, until reaching a saturated speed...

In physical experiments, there is a ring-shaped accelerator. The initial method was to manually place the steel ball to accelerate it to a relatively high energy device. The ring-shaped track can allow the steel ball to repeatedly pass through the same acceleration gap, so that the energy of the particles can be increased multiple times. This product is a simulated acceleration demonstration effect.
