8-coil Circular Electromagnetic Accelerator Scientific Experiment Tool DIY Physics Toy with High Magnetic Beads
Features:
.Acrylic sheet on the back is the bottom plate, and the supporting positions are buckled together. The overall structure is strong and durable; each coil of the precision circuit has a separate control circuit board, which does not affect each other, and is low-voltage and reliable. .Using high-temperature enameled wire coil and stainless steel wire production, circular track, low power, low heat, no rust, long service life. The same material can reduce friction, and the response is more sensitive. .Acrylic structural parts are very simple, the display is transparent, and the whole body is stronger; the open track, easy to start, can be moved by hand, intuitive and visual, and the presentation is clear and easy to understand. .Like the principle of the electromagnetic gun, there is an infrared sensor at one end of the coil. When the sensor senses that the small ball approaches the coil, the coil is energized immediately, and the steel ball is electromagnetically attracted to pass through the coil. After passing through the coil, the power is cut off immediately, and the iron ball will roll to the next coil due to inertia, so that the speed will be accelerated again and again, and the speed will get faster and faster. The more coils, the faster it will accelerate, until a saturation speed is reached. .The circuit boards are controlled separately and will not affect each other. After plugging in the power, the coil circuit board will show a red light, which means that the machine starts to work. After putting the steel ball in, push the steel ball, and the blue light will blink every time a coil is passed. Represents normal operation. The circular orbit allows charged particles to repeatedly pass through the same acceleration gap and the particle energy will be able to increase multiple times. .Significance and Value: Can be used for physics teaching or as a gift to physics lovers. .Age: 14+

The device is built on an acrylic base about 60 cm in diameter, with 8 coils equally spaced around the ring. There is a wire track that the ball runs on. The device came with 8 steel balls, 4 large and 4 small. The included power supply is marked as supplying 24 volts and 5 A. Everything was completely assembled except for some minor damage as described below.
Though it was packed in polyethylene foam, there was slight damage from shipping. Not too surprising since it is shipped from China. The base and brackets are acrylic glued together. About 1/3 of the support brackets had broken off the base. This was easily fixed with plastic weld (methylene chloride) which I happened to have handy. I applied some to the joints with a syringe and held for 30 seconds to repair. One picture shows the repaired bracket, with the coil circuitry in the background. The 3 wire track rings have one junction each, and 2 of the junctions had come loose - again easily fixed with the plastic weld. The other picture shows one of the repaired junctions. After repairs, I powered it up and it worked great!
Each coil has an LED pair on one side to detect the presence of the ball. When the LEDs are blocked, current flows to the coil and the ball is accelerated into the coil. When the LEDs are no longer blocked the current shuts off. I found that the smaller balls would accelerate to about 45 rpm while the larger ones were about 150 rpm. It's pretty foolproof - there's no timing to worry about, since each coil has its own sensor. The ball accelerates until the losses due to friction equal the energy imparted every time the ball gets a kick from the magnet coils.
Satisfied customer, though I would recommend having some plastic weld solution handy.
