Magnetic holding force is one of the most important reference values when selecting magnetic bases, rubber coated magnets, and other magnetic holding products. However, this value should not be treated as the guaranteed working load in every application. In real working conditions, magnetic holding force can change significantly. The actual performance depends on the steel…
Overview of Magnetic Shielding Magnetic shielding is a method used to control how magnetic fields spread in space. In many cases, it does not completely block a magnetic field like a wall blocks light. Instead, it provides an easier path for magnetic flux, guiding part of the magnetic field through a suitable material and reducing…
Overview of Air Gap in Magnetic Holding Systems Air gap is a basic but often underestimated factor in magnetic systems. It refers to the non-magnetic distance or layer between magnets and the objects they need to attract, hold, sense, drive, or interact with. In practical use, this gap is not always only air. It may…
Overview of Magnetic Permeability Magnetic permeability indicates how readily a material can carry magnetic flux. In simple terms, a material with high magnetic permeability can provide an easier path for magnetic flux, while materials with very low permeability do not guide magnetic flux effectively. In magnetic holding products, this concept is important because the magnet…
Overview of Overmolded Magnets Overmolded magnets are magnetic components made by molding rubber, plastic, elastomer, silicone, or another suitable material around one or more permanent magnets or magnetic assemblies. Instead of using bare magnets alone, the surrounding material can provide surface protection, friction, impact resistance, insulation, positioning features, or a more application-ready structure. At WZ…
Recent supply-chain headlines have made the phrase “the 4 Magnetic Rare Earths” much more visible than before. A recent Reuters report on the Serra Verde and USA Rare Earth deal used this wording for the four major rare earths needed to make permanent magnets, and the companies themselves have used very similar language in their…
Can You Still Source Samarium Cobalt Magnets in 2026? Yes, Samarium Cobalt (SmCo) magnets can still be sourced in 2026, but the sourcing process is no longer as simple as it used to be. For many years, buyers treated Samarium Cobalt magnet sourcing mainly as a technical and commercial process. They selected a grade, confirmed…
Ferrite magnets are widely known for their cost-effectiveness and relatively stable supply, which is one of the main reasons they are used in such a wide range of industrial and commercial applications. However, ferrite magnet prices are not always as stable as many buyers expect. When upstream raw materials become more expensive or harder to…
Many customers are confused and don’t know what to choose between N50 and N52. They know these are both strong magnets, but they don’t know what the difference is, and they don’t know which one they should use. N52 magnets are generally stronger than N50 magnets, making them the preferred option for applications requiring maximum…
