When used with a Hall sensor, it can generate magnetic force in a better position, so that the running effect is better. Ball bearings boast low friction, quietness and durability, and provide strong support for smoother operation. Both sides of this product are supported by high-precision cut acrylic brackets, which have high transparency, no deformation, and beautiful appearance. The beam support is a four-branched carbon fiber column, which is strong, durable and stable, showing high-end atmosphere. Product Principle: If a current (lv) is applied to the conductor (d) in the magnetic field (B), the direction of the magnetic field is perpendicular to the direction of the applied voltage. Then another voltage (UH) will be generated in the direction perpendicular to both the magnetic field and the direction of the applied current. People call this voltage the Hall voltage, and this phenomenon is called the Hall effect. It’s like a road. Everyone is evenly distributed on the road, moving forward. When there is a magnetic field, everyone may be pushed to walk on the right side of the road. Therefore, there will be a voltage difference on both sides of the circuit (conductor). This is called the “Hall Effect”. The Hall device made according to the Hall effect uses a 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. A multi-cylinder engine is an engine with more than two cylinders, which is composed of several identical single cylinders arranged on a body to share the output power of a crankshaft. Product Applications: * The design of this product is small and flexible, making it more delicate as a decoration. * High-tech ornaments combining magnetic field and electric field. * The product is highly educational. Can be given to children or students for demonstration. * Cultivate interest in scientific knowledge. Product Features: 1. This product uses 5V power supply, breaking away from the restriction of sockets. Low power. 2. Low friction, quiet and durable. 3. You can choose from a variety of specifications and sizes. 4-coil, 8-coil, 12-coil are optional. 4. The engine adds LED lights. After power on, lights turn on. Full of a sense of technology.
