Method 2: High temperature demagnetization

High temperature demagnetization can cause the magnetism of the magnet to disappear and then re magnetize it. The following methods can be used for high-temperature demagnetization:1. Place the magnet in the oven and heat it to 70-80 degrees Celsius.2. Hold for 10-15 minutes, then remove and cool.3. Then use the method of re magnetization for magnetization.Method 3: Demagnetizer demagnetizationA demagnetizer can completely eliminate the magnetism of a magnet and then re magnetize it. The following methods can be used to demagnetize the demagnetizer:1. Place the magnet in the demagnetizer.2. Press the demagnetization button and hold for a certain period of time.3. Remove the magnet and recharge it.

Magnets can be manufactured by the following methods

Casting method: This is the most common method of making magnets. Melt appropriate proportions of iron, nickel, cobalt, and other materials, then pour them into the mold for cooling and solidification to form the desired shape of the magnet.Pressing method: Mix magnetic powder (such as iron powder, iron oxide, etc.) with polymer plastic or adhesive, and then press it into the desired shape of the magnet blank through a pressing machine. Finally, after sintering or heat treatment, the magnet has a certain degree of magnetism.Stretching method: By stretching a metal material with magnetism, it forms a magnetic domain arrangement during the stretching process, thereby obtaining magnetism.Powder metallurgy method: Mix magnetic powder with an appropriate binder, and then make a magnet through processes such as pressing and sintering.Regardless of the manufacturing method used, magnetization treatment is ultimately required to enhance the magnetic properties of the magnet. Magnetization can
