In this magnet industry, you will always see magnets listed with a maximum pull force, remanence, and gauss rating. So what’s the difference among them? What is Gauss? Gauss is a measure of magnetic induction and a value of density. Simply put, Gauss represents the number of magnetic field lines per square centimeter, emitted by […]

Flux Density Test (Gaussmeter) The surface flux density or the flux density at a certain distance from the magnet can be obtained using a Gaussmeter and an Axial or Transverse probe. The probes contain a Hall Effect device whose output voltage is proportional to the flux density. Figures 1a and 1b show the placement and […]
In many applications in life, the orientation of the magnet’s poles may not matter – as long as the magnet attracts where it is needed. In other cases, however, the directionality of the magnet is an important component of the intended application. Understanding the conventional and specialized magnetization directionality options available helps to ensure successful […]
When you are trying to figure out which neodymium magnets to select for your design needs, you would always see the term “grade” or “N rating” from any supplier or manufacturer. Besides a few other criteria like coating, tolerance, and desired material grade must be defined for a neodymium magnet. The material grade is the […]
