The bearing used is a ball bearing, which has the advantages of low friction, quietness and durability, and provides strong support for smoother operation. The high-quality cutting acrylic support is used on both sides of the product, which has high transparency and no Deformed, beautiful appearance, the beam bracket is four carbon fiber columns, durable and stable, showing high-end atmosphere.\u003cbr\u003e3, Working Principles: If a current (Iv) is applied to the conductor (d) located in the magnetic field (B), the direction of the magnetic field is perpendicular to the direction of the applied voltage, then perpendicular to the magnetic field and perpendicular to the direction of the applied current. Another voltage (UH) is generated in the direction. People call this voltage the Hall voltage. This phenomenon is called Hall effect. Just like a road, originally everyone is evenly distributed on the road, moving forward; When there is a magnetic field, you may be pushed to the right side of the road. Therefore, voltage difference will be generated on both sides of the circuit (conductor). This is called the hall effect. According to the Hall effect, the Hall device uses the magnetic field as the working medium to convert the motion output of the object into a digital voltage output, so that it has the functions of sensing and switching. The multi-cylinder engine has two or more cylinder engines, which are composed of several identical single-cylinders arranged on one body and share the root crankshaft output power.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003eItem Name: Electromagnetic Engine Model\u003cbr\u003eMaterial: Acrylic + Copper + Stainless Steel\u003cbr\u003eSize: 28 x 10.8 x 11cm\u003cbr\u003eWeight: 920g\u003cbr\u003ePacking: Carton Box\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePackage Content:\u003c\/strong\u003e\u003cbr\u003e1 x Electromagnetic Engine Model\u003c\/p\u003e","brand":"enginediy","offers":[{"title":"Default Title","offer_id":27823893741632,"sku":"33ED2665942","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0175\/0718\/8800\/products\/4b66d631-a52d-431e-8973-c193511443f8.jpg?v=1608192240"},{"product_id":"mendocino-motor-solar-magnetic-levitation-motor-engine-science-toy","title":"Mendocino Motor Solar Magnetic Levitation Motor Engine Science Toy","description":"\u003ciframe allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\" frameborder=\"0\" height=\"480\" src=\"https:\/\/www.youtube.com\/embed\/dnqwnLZofSk\" width=\"850\"\u003e\u003c\/iframe\u003e\n\u003ch3\u003e\u003cstrong\u003eMendocino Motor Solar Magnetic Levitation Motor Engine Science Toy\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eEnginediy Engine (sku:33ED2609610) is \u003cspan\u003ea real solar magnetic levitation motor engine model, pure handmade, composed of 6 solar silicon wafer, copper coils, shaft, NdFeB magnet, acrylic stent.

It was conceived in the late 19th century and produced by various companies from the 1890s through approximately the 1940s. The name comes from the speed control on these engines: they fire (\"hit\") only when operating at or below a set speed, and cycle without firing (\"miss\") when they exceed their set speed. This is as compared to the \"throttle governed\" method of speed control. The sound made when the engine is running without a load is a distinctive \"POP whoosh whoosh whoosh whoosh POP\" as the engine fires and then coasts until the speed decreases and it fires again to maintain its average speed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e1, STABLE STRUCTURE:\u003c\/strong\u003e The engine can be disassembled and can be used for DIY , the structure design is stable, and the surface has anti-rust treatment.\u003cbr\u003e\u003cstrong\u003e2, SIMPLE OPERATION:\u003c\/strong\u003e Place the engine on a lug boss, leave the wheel in a suspended state, inject gasoline or diesel or kerosene into the single cylinder, and then manually rotate the wheel (may take two or three attempts) and the engine will start.
