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…

What Is Magnetic Permeability and Why Are Some Materials Magnetic When Others Are Not?

A Closer Look at Magnetic Permeability and Why Some Types of Materials Are More Attracted by Magnets Than Others 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 […]
