Technical Field

[0002] A bar magnet is a rod-shaped magnetic object consisting primarily of a core and a shell. The core is typically made of high-performance permanent magnetic materials such as ferrite and neodymium iron boron. These materials possess strong magnetism and can generate a powerful magnetic field. The shell, typically made of stainless steel or plastic, protects and secures the core. Due to the properties of magnetic materials, when exposed to a magnetic field, the magnetic domains within the bar magnet align, generating magnetism. This attracts ferromagnetic materials such as iron, nickel, and cobalt, adsorbing them to the surface through the magnetic field.
