Open track, easy to start, just dial by hand, intuitive visual sense, easy to understand the demonstration. The coil is made of high temperature enameled wire, low power, low heat, no rust, long service life. Adopting stainless steel wire to make the ring track, fast reaction speed and smooth running. Precision circuit board, each coil a separate circuit board, do not affect each other, low voltage and reliable. The back acrylic plate is the base plate, the support position is connected with the card buckle, the overall structure is sturdy and durable. DIY Six Coils Circular Accelerator Electromagnetic Cyclotron Scientific Experiment Equipment Physics Teaching Aids Model Description: This Electromagnetic Cyclotron is the same principle as the Electromagnetic Cannon, with an infrared sensor at one end of the coil. When the sensor senses the ball approaching the coil, the coil will be energized immediately, the ball will be attracted by the electromagnetism to pass through the coil. When it passes through the coil, the power will be cut off immediately, and the ball will roll to the next coil because of inertia, and the speed will be faster and faster, the more coils you have, the faster you will be accelerated until a saturation speed.
