detailed description

The invention provides a nanofluid magnet wheel generator and a manufacturing method thereof.

Since the frictional motion between the tire and the road surface 004 generates a temperature when the vehicle is running, the temperature of the fluid magnet in the tire is also increased, and the magnetization magnetism, specific gravity, viscosity, boiling point, flow point, vapor pressure, etc. are followed. The change occurs so that the fluid magnet 003 will move in the opposite direction to the coil 002 set in the tire at a certain speed. G卩: The coil 002 rotates in the same direction as the wheel tire 001, and the fluid magnet 003 moves in the opposite direction to the coil 002, so that the relative movement between the fluid magnet 003 and the coil 002 occurs. According to Faraday's law of electromagnetic induction, the result of this motion will generate an electromotive force 005 in the coil 002, and then output the current 006 generated in the coil 002 through the conductive brush and store it in the battery as the driving force of the vehicle.
