Anisotropy
Anisotropic materials have different properties in different directions, Has optimal magnetic performance in a specific direction. Neodymium magnets are anisotropic and have a "preferred" direction of magnetization before being magnetized.
Isotropic
A material that can be magnetized along any axis or direction of the magnet (magnetically undirected material), as opposed to an anisotropic magnet.

Curie Temperature (Tc)
The temperature at which a magnet loses all magnetic properties.
BH Curve
A curve that plots the value of the magnetic field (H) against the resulting flux density (B), which describes the quality of any magnetic material.
Demagnetization Curve
The second quadrant of the hysteresis loop, which generally describes the behavior of the magnetic properties in actual use, is also known as the B-H curve.
Magnetization curve
A curve that describes the process of magnetization of a material in the presence of an applied magnetic field.
Maximum Operating Temperature
Also known as the maximum operating temperature, it refers to the highest temperature at which a magnet can operate normally while maintaining its magnetic properties and structural integrity.
Irreversible loss
Is a permanent reduction in the magnetic properties (e.g., flux density, coercivity, etc.) of a magnet when it is exposed to certain conditions (e.g., high temperatures, strong external magnetic fields, or mechanical stresses) that cannot be restored to its original state after these conditions are removed.
Orientation
A term used to describe the direction of magnetization of a magnet.
Plating/Coating
Magnet plating or coating refers to plating or coating the surface of a magnet with a substance to improve its properties or protect its surface.

Temperature Coefficient
Describes the degree to which magnetism varies with temperature.
Hard Magnetic Materials
Also known as permanent magnetic materials, these are materials that retain their magnetic properties after magnetization and are not easily reverse magnetized.
Soft magnetic material
Materials that are easily magnetized but also easily demagnetized, usually with low coercivity and high permeability.

Magnetic Field Strength
A physical quantity describing the strength of a magnetic field, a vector quantity of a magnetic field, indicating the magnitude of the magnetic force per unit length, usually expressed by the symbol H, in amperes per meter (A/m).
Magnetic induction intensity
Also known as magnetic flux density, it expresses the amount of magnetic flux per unit area, usually denoted by the symbol B, and is measured in Tesla (T), with 1T = 10000 gauss.
Surface magnetism
Refers to the properties and distribution of the magnetic field at the surface of a magnet and describes the strength of the magnetic field at the surface of a magnet, as measured with a Gaussmeter/Tesla meter.
Sintered Magnets
Magnets manufactured through the powder metallurgy process, a specific process that involves pressing and molding powders of magnetic materials and then sintering them at high temperatures, can produce high-performance magnets.
Bonded Magnets
Magnets manufactured by mixing magnetic powder with a binder and then pressing and molding the magnets without high-temperature sintering in the manufacturing process.
Injection Molded Magnets
It is a type of magnet that can be easily manufactured in complex shapes by mixing magnetic powder with thermoplastic (e.g., nylon, polyamide, etc.) and using an injection molding process.
Magnet Grade
It is an important index used to express the performance of magnets, usually consists of a letter and a set of numbers to describe the magnet's magnetic energy product, coercivity, remanent magnetism and other characteristics.
