The transportation of magnetic materials through air presents unique challenges owing to the potential interference they can cause with an aircraft’s navigation system and control signals. Recognizing these challenges, the International Air Transport Association (IATA) classifies magnetic materials as class 9 hazardous goods, imposing specific regulations and guidelines to maintain safety standards during air transit. This article guides you through meeting these standards, ensuring your magnetic shipments remain compliant. Understanding the Regulatory Landscape The IATA has laid down two critical

In the intricate world of magnet production and distribution, the packaging and transportation phase holds paramount importance. Given that the magnets possess a strong magnetic force, proper packaging is imperative to prevent any potential adverse effects on the surrounding environment and other equipment. In this article, we delve into the conventional packaging process that adeptly utilizes demagnetizing packaging, effectively altering the magnetic field distribution of the magnets without eliminating their magnetic properties, akin to a Faraday cage offering magnetic shielding.

At EPI Magnets, we’re not just suppliers, we’re experts dedicated to understanding every facet of the magnetic materials we work with. Today, we delve deep into the physical properties of sintered Neodymium-Iron-Boron (NdFeB) magnets, a critical functional component in a wide array of equipment including motors, acoustic devices, magnetic assemblies, and sensors. Throughout their lifecycle, these magnets face a barrage of environmental factors – from mechanical stresses to thermal fluctuations, and the relentless push and pull of alternating electromagnetic fields.

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

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.
