Most modern magnet materials have a “grain” in that they can be magnetized for maximum effect only through one direction. This is the “orientation direction”, also known as the “easy-axis”, or “axis”.
Un-oriented magnets (named as “lsotropic magnets”) are much weaker than oriented magnets, and can be magnetized in any direction. Oriented magnets (also named “Anisotropic magnets”) are not the same in every direction-they have a preferred direction in which they should be magnetized.
Most commonly, Gaussmeters, Magnetometers, or Pull-Testers are used to measure the strength of a magnet.
(1) Gaussmeters measure the strength in Gauss;
(2) Magnetometers measure in Gauss or arbitrary units (so its easy to compare one magnet to another);
(3) Pull-Testers can measure pull in pounds, kilograms, or other force units.
Special Gaussmeters can cost several thousands of dollars. Helmholtz Coils, search coils and permeameters are also used to make sophisticated measurements of magnets.

NdFeB Block Magnets are characterized by three main characteristics. These are known as the:
(1) Residual Induction (symbol Br, and measured in Gauss). This is an indication of how strong the magnet is capable of being.
(2) Coercive Force (symbol Hc, and measured in Oersteds). This is an indication of how difficult it is to demagnetize the magnet.
(3) Maximum Energy Product (symbol BHmax, and measured in Gauss-Oersteds). This is an indication of what volume of magnet materials is required to project a given level of magnetic flux.
