Background

In general, a magnet capable of maintaining its magnetism for a long period of time is called a permanent magnet. Such as natural magnetite (magnetite), artificial magnet (alnico), and the like. Besides permanent magnets, there are electromagnets that are magnetic only when energized. The permanent magnet is also called a hard magnet, so that the permanent magnet is not easy to lose magnetism and is not easy to be magnetized. However, if the permanent magnet is heated above the curie temperature or is located in an environment of high magnetic field strength in the opposite direction, the magnetic properties thereof are also reduced or lost. Some magnets are brittle and may crack at high temperatures. The maximum service temperature of alnico magnets exceeds 540 ℃ (1,000 ° F), samarium cobalt magnets and ferrites are about 300 ℃ (570 ° F), and neodymium magnets and soft magnets are about 140 ℃ (280 ° F), but the actual values will still vary according to the crystal grains of the material, and the application range of permanent magnets is various, including televisions, speakers, radios, leather bags, data line magnetic rings, computer hard disks, mobile phone vibrators, etc. Permanent magnets such as loudspeakers use the principle of movement of an energized coil in a magnetic field to produce sound. When the current in the coil changes, the permanent magnet on the loudspeaker generates a magnetic field which acts with the current, so that the relative position of the coil and the magnet changes, the cone on the loudspeaker is driven to vibrate, air is pushed, the vibration is propagated, and the human ear can hear the sound. In a word, the permanent magnet is ubiquitous in life, and brings convenience to production and life of people.
