When an electric current passes through the coil on the transmitting side, it generates an alternating magnetic field. The coil on the receiving side is placed in this alternating magnetic field. An induced current is generated in the receiving coil. In this way, it could achieve wireless transmission of electrical energy.
Common magnet materials mainly include neodymium iron boron, samarium cobalt, aluminum nickel cobalt , and ferrite.
- Neodymium Magnets: It possesses extremely high magnetic energy product and coercivity. It is also the strongest permanent magnetic materials. It is typically used in applications that require strong magnetic attraction.
- Samarium Cobalt Magnets: Compared with neodymium magnets, samarium cobalt magnets is slightly weaker in the magnetic properties, but they offer better temperature stability and corrosion resistance. Normally used in high-temperature or humid environments.
- Aluminum Nickel Cobalt Magnets: AlNiCo magnets have excellent temperature resistance and corrosion resistance, but their magnetic properties are slightly weak.
- Ferrite Magnets: Ferrite magnets are featured by low cost and easy of manufacture.
We will develop a detailed magnet solution based on the specific application scenarios and device dimensions. In some compact designs, a ring-shaped or array-type magnet arrangement may be adopted to reduce the occupied space and improve overall aesthetics. We also try to use the intelligent control system to adjust the magnet strength and direction.
