12 Coils Electric Motor Teaching Model Aid Toy V-type Electromagnet Engine Model

12-Coil Version Motor Model V-Shaped Electromagnet Engine Model Teaching Aid Model Toy 5V TECHTONGDA ® ITEM DESCRIPTION The product design is small and flexible, more exquisite, easy to carry, and more exquisite as decoration. High-tech mold combining magnetic field and electric field, the product has strong edutainment, suitable for demonstration teaching, and increase students’ interest in science. Low friction, quiet and durable, long service life. The engine model adopts 110V-240V to 5V voltage, low power and high safety; Increase LED lamp design, full of scientific and technological sense; The design is small and flexible, exquisite and beautiful, and the high-tech decoration combining magnetic field and electric field can be used for teaching or decoration, and increase the interest in science. ITEM PARAMETER Coil: 12 Voltage: 100-240V to 5V Power: 6W Package size: 20″*9″*9″ (53CM*22CM*22CM) Net weight/Gross weight: 3LB(1.3KG) / 5LB(2.3KG) ITEM DETAILS LED Lights Non-Slip Low Power The engine has increased the design of LED lights, and the lights will light up after the power is turned on, which is full of scientific and technological sense. There are four non-slip foot pads at the bottom, which will not slide when displaying the mold, making it safer to use. The use of 5V power supply, get rid of the restrictions of the socket, low power, high safety; Low noise, quiet and durable. ITEM 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 road (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. ITEM NOTE 1. Please handle with care, please not disassemble by yourself. 2. Please not remove the sensor. 3. Please not touch the inside of engine after powering on. 4. Place it on a balanced desktop to use. 5.
