All materials are defined as being magnetic in that they respond to the application of an applied magnetic field differently to that of air or vacuum. Only selected elements or alloys have useful magnetic properties in engineering applications. Magnetic materials which are easily magnetized and the magnetized are often termed soft. Conversely, those magnetic
EA Magnetics carries a wide range of sizes in almost all magnetic materials. The following chart can be used as a guide for determining the relative strength of various materials in relation to other magnetic materials available on the market.

A test or combination of test methods should be based upon the criticality of the requirement, and the cost and ease of performing tests. Ideally, the test results should be able to be directly translated into a functional performance of the magnet. A sampling plan should be specified which inspects the parameters that are critical
