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":179.99,"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":"labs-demonstration-motor-generator-ac-dc-generator-demo-set","title":"Labs Demonstration Motor Generator Activity Model AC\/DC Generator Demo Kit for Student","description":"\u003cp\u003e\u003cstrong\u003eLabs Demonstration Motor Generator Activity Model AC\/DC Generator Demo Set for Student\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLabs demonstration motor generator activity model allows students to easily compare and contrast an AC generator and a DC generator. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e1, LABS MOTOR GENERATOR DEMONSTRATION:\u003c\/strong\u003e It can demonstrate the structure and principle of DC generator and AC generator.

Originally described by E. Marx in 1924, Marx generators are probably the most common way of generating high voltage impulses for testing when the voltage level required is higher than available charging supply voltages. Furthermore, above about 200 kV, the discharge capacitor becomes very expensive and bulky.

The mobile phone can connect to the Tesla coil via Bluetooth, and the Tesla coil can be connected to Tes in a space of about 10 meters. Pull the coil to play music, no longer bound by the audio cable\u003cbr data-mce-fragment=\"1\"\u003e .Input audio signals to the circuit through the Bluetooth module, no matter what brand of mobile phone is used to link the Tesla coil, the arc will emit a qualified volume, which solves the problem of low volume caused by different audio output power of different mobile phone brands\u003cbr data-mce-fragment=\"1\"\u003e .You can also connect the audio of MP3, computer, mobile phone through audio cable, let the arc sing and play music, and become a plasma speaker. The top of this coil is designed with different discharge terminals that can be replaced, thus realizing the effect of ion windmill and ion rosette\u003cbr data-mce-fragment=\"1\"\u003e .Ion windmill: The arc is a high-temperature plasma, which can heat the air to generate thrust. We let the arc direction at both ends of the ion wind spray to make it spin\u003cbr data-mce-fragment=\"1\"\u003e .Ion Wreath: We use a thin, flexible metal wire as the discharge end. When the coil starts to work, the arc sprays from the top to generate thrust.

It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast, if the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by the power protection of excessive power.

Exhaust Stroke: Due to the inertia of the rotating mechanism, the crankshaft passes through the bottom dead center, causing the piston to move upwards.
