What is Remanence (Br)?
What is Remanence (Br)? There are four main indicators for measuring the performance of permanent magnets: remanence (Br), coercivity, intrinsic coercivity, and maximum magnetic energy product. In our last article, we’ve introduced what is maximum magnetic energy product, so in today’s article, we’ll take a look at what is remanence (Br). The Concept of Remanence (Br)

What is Maximum Energy Product (BH)max?
What is the Maximum Energy Product (BH)max? There are four main indicators for measuring the performance of permanent magnets: remanence, coercivity, intrinsic coercivity, and maximum energy product (BH)max. In the following posts, we will introduce these concepts and their applications one by one. In today’s article, let’s take a look at the maximum energy product

A Brief Introduction to Ferrite Magnets
A Brief Introduction to Ferrite Magnets Compared with other permanent magnets like Neodymium Magnets, SmCo Magnets, and AlNiCo Magnets, Ferrite Magnets are hard and brittle and have lower magnetic energy. However, they are not easy to demagnetize and to be corroded, and the production process is simple and low in price. Therefore, ferrite magnets have the

Surface Treatment of NdFeB Magnets – Passivation
Surface Treatment of NdFeB Magnets – Passivation In order to improve the corrosion resistance of NdFeB magnets, it is usually necessary to treat the surface of NdFeB magnets. Common surface treatment methods for NdFeB magnets include phosphating, electroplating, electrophoresis, and vapor deposition. In our last article, we’ve introduced the electrophoresis, so in this article, we will introduce

What Objects Are Attracted To Magnets?
What Objects Are Attracted To Magnets? Magnets are very useful in our lives. For example, we can use magnets to attract iron nails, iron keys, and iron scraps, etc. So in addition to these objects that are obviously composed of iron, what other objects can be attracted to magnets? First of all, let us first analyze
