Sintered Neodymium (NdFeB) magnets, known for their high magnetic energy density and excellent operational characteristics, are widely used in various fields including household appliances, transportation, healthcare, and aerospace. To objectively assess the suitability and quality of these magnets, various tests are conducted, generally categorized into three aspects: appearance and physical properties, magnetic properties, and auxiliary performance tests. Testing Appearance, Dimensions, and Physical Properties The appearance, dimensions, and physical properties are fundamental for the use of NdFeB products. Good products must

Magnetism, a phenomenon that has fascinated humanity for centuries, is still a subject of intrigue and study. One of the most common queries that arise is how to measure the strength of a magnet. This article delves into the intricacies of measuring magnets, offering insights into the tools used and the factors that can influence readings. Understanding Surface Field The Surface Field of a magnet refers to the theoretical strength of the magnetic field right at the magnet’s surface. This

When it comes to understanding magnets, the concept of pull force is often a sticking point. How much weight can a magnet support? What factors influence a magnet’s pull force? Here at EPI Magnets, we are committed to helping you understand these complexities.

Have you ever wondered how to effectively mount an object to a vertical surface using magnets? Understanding the nuances of this can be a bit challenging, but here at EPI Magnets, we’ve simplified it into two key principles: leverage and friction. In this comprehensive guide, we aim to make this task easier for you, incorporating illustrative visuals for a better grasp of these concepts. Leverage and Friction The cornerstone of effectively using magnets to hold an object on a vertical

Neodymium magnets, or NdFeb magnets as they are scientifically known, come in a diverse array of shapes and sizes. Each unique shape has its own set of potential magnetization orientations. The magnetic force of a magnet is most potent when its pole directly contacts a surface of the opposite polarity. For example, a disc or ring magnet with axial magnetization performs optimally when one of its flat surfaces is in direct contact with the flat surface of another disc or

Hello and welcome to EPI Magnets. As a leading company in the magnet industry, we want to ensure that our customers and readers alike have a comprehensive understanding of key magnetic parameters. In this article, we will delve into the intriguing concepts of Surface Field and Magnetic Flux. Surface Field Surface Field, at its simplest, is the magnetic induction strength at the surface of a magnet. It’s defined as the magnetic flux passing through a unit area, hence it’s also

Understanding the properties of permanent magnetic materials like Neodymium Iron Boron (NdFeB) is critical to their use in a variety of applications. These properties are typically quantified by four key parameters: remanence (Br), coercivity (Hcb), intrinsic coercivity (Hcj), and maximum energy product (BH(max)). To truly grasp these indicators, we need to understand the demagnetization curve – a tool that effectively reflects the overall performance of a magnet. Understanding the properties of permanent magnetic materials like Neodymium Iron Boron (NdFeB) is

Neodymium magnets, also known as NdFeB magnets, are a powerful and versatile class of permanent magnets. They have become an essential component in a myriad of industries, from consumer electronics to renewable energy. In this article, we’ll explore the different Neodymium magnet grades, their unique properties, and how to choose the right grade for your application. We’ll also discuss the impact of temperature on their performance, ensuring you have the knowledge to make informed decisions about your magnetic needs. The

Neodymium Iron Boron (NdFeB) magnets necessitate the use of a protective layer or surface treatment to guard against potential damage from corrosion. Exposure to atmospheric moisture alone can lead to signs of corrosion in an uncoated NdFeB magnet. Moreover, these magnets are exceptionally susceptible to corrosion in marine environments. Corrosion in these magnets, akin to rusting, results in an irreversible alteration of their structure. This leads to a gradual decline in their magnetic capabilities, causing the magnet to weaken over

Neodymium magnets are the strongest permanent magnets we sell and the surprisingly strong force between them may cause serious personal injuries, as well as to the magnets themselves. Reviewing this checklist to help customers handle these magnets properly is strongly recommended. Powerful attraction forces can cause serious injury. Never put your fingers or any other body parts between two magnets. Neodymium magnets will slam together from several inches to feet apart, the huge impact may cause the body to pinch,
