Magnetic Saturation: Understanding Practical Limitations to How Much Induced Magnetism Can Be Achieved in a Workpiece

There are limits to how much induced magnetism is possible in different materials and similar workpieces of varying size, shape and configuration. The principle of magnetic saturation observes that there is a point of diminishing returns at which attempting more externally applied magnetic field (H) will give rise to no additional magnetic induction (B). Increasing the thickness of a workpiece is generally beneficial. However, these changes will likely impact cost, mass, and possibly ease of manufacturing. It is therefore beneficial to understand and control for the magnetic saturation of materials during the design stage…

Magnetic Permeability:  Why Are Some Materials Attracted By A Magnet And Others Are Not?

Magnetic Induction - Permeability Plot

Two magnets attract to each other because their fields interact.  Usually materials that are not magnets do not have a net external field, and obviously, they do not attract to things; however, some metal alloys can have a net field created by applying an external field.  This induced field is only present when the external […]

Did You Know?

Without proper design considerations, your magnet will fail. High temperatures, other magnetic fields and aggressive environments can cause magnets to fail.
