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…

Magnet Safety 101: How to Safely Handle Magnets

Magnets are produced in a wide array of sizes, shapes, and strengths, but there are similarities between all magnetic materials.  They are all relatively brittle which when coupled with their magnetic strength present a number of issues.  They also invoke curiosity, and who hasn’t heard the adage of what curiosity did to the cat?  Handling […]

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 […]

Essential Advice for Choosing the Best Magnet Vendor

So the right type of magnet has been designed or selected for your application and now you’ve begun the task of finding a company that can supply the part, right? Well, it’s not always that easy as magnets are unlike other commodities and, in fact, they should not be treated as commodities at all. At […]
