The wind industry requires an astounding amount of rare earth minerals, primarily neodymium and dysprosium, which are key components of the magnets used in modern wind turbines. Never handle neodymium magnets near electrical or electronic devices. This is why China has focused on them in the past and restricted their export, and dominate rare earths production. Your country may have specific laws regarding the use or sale of neodymium magnets, so its essential to research before purchasing them online or from a local vendor. The CSPC gave the final ruleconcerning these magnets on October 3rd, 2014, stating that if a magnet set contains a magnet that fits within the CPSCs small parts cylinder, each magnet in the magnet set must have a flux index of 50 kG2 mm2 or less.. Wind energy is not nearly as clean and good for the environment as the wind lobbyists want you to believe. Magnetization technology refers to the use of a magnetic field to magnetize a substance to change the bonding state and properties of the magnetized substance, or change the atomic and electronic states, promote the chemical reaction of the substance, or change the crystal form or freezing point of the substance. For example, neodymium magnets are widely used in electric bicycle motors, elevator traction machine motors, refrigerator air conditioner motors, and wind-driven motor, etc. Grade N52. The technique of using magnetic methods to separate ferromagnetic substances from non-ferromagnetic substances is called magnetic separation technology. This ban, however, was overturned in 2016.
