How often should I be cleaning my magnets? CLEANING MAGNET This is another question that is dependent upon your individual process. Obviously the more metal you receive or produce in your process, the more frequently the magnets need to be cleaned. A general rule is the more frequently, the better. As a magnet gathers ferrous [...]
Bonded Magnet Material And Process Options Injection Molding Compression Bonding Calendering Extrusion Bonded Magnet Material And Process Compression Bonding or Injection Molding? Injection Molding • Complex forms with good geometrical tolerances • Multi‐cavity tooling • Over and insert molding But • Expensive tooling • Lower magnetics (66% volume loading of magnetic powder) • NdFeB and ferrite Compression Bonding • Thin walled large L/D ratio rings • Simple low cost tooling • Higher magnetics (75% volume loading of magnetic powder) But • Simple geometries • Value added operations during pressing very difficult • NdFeB only CLEANING MAGNET TESTING MAGNET How long should my permanent magnet last? MAGNETIC APPLICATIONS
DIY Foxy Magnetic Mug Sleeve Sometimes you just can’t wait to enjoy that first (or second, or third) cup of coffee or tea. However, using a conventional mug is not without its problems. The handles are often too small to accommodate a comfortable grip and the mug itself takes forever to cool off. By following [...]
What is the Geographic (True) North Pole? The Earth rotates on the geographic north and south poles. The geographic north and south poles are where lines of longitude (meridians) converge in the north. The south and north pole are directly opposite to one another. The North Pole is located in the middle of the Arctic [...]
What Are Bonded Magnets Anyway? • Bonded magnets are composites of a permanent magnetic powder(s) embedded in a non‐magnetic matrix. • The matrix is typically a thermoplastic or elastomeric binder. • Common processing techniques are extrusion, injection molding, compression bonding, and calendering. • Exhibit excellent mechanical properties compared to fully dense rare earth and ferrite magnets. • End product has good finish and dimensional tolerances requiring no finishing operations. • Injection molded magnets can be formed into complex shapes and be insert or over molded directly onto other components to produce assemblies. • The non‐magnetic binder lowers the density of the magnet and dilutes the contribution of the magnetic powder. • They generate less magnetic output per unit volume than fully dense magnets. • The two most common magnetic powders are isotropic NdFeB and hard ferrite.

Kubonets magnetic wall hook - Neodymium magnets are great by themselves but this causes some problems, they are not easy to handle, they can break when they snap together and lastly they can't be mounted as easily. So thats what Kubonets are for: Super strong, very functional, easy to handle magnets. Not to mention that [...]
What is the Magnetic North Pole? The Earth is one big magnet. The Magnetic North Pole (also known as the North Dip Pole) is a point on Ellesmere Island in Northern Canada where the northern lines of attraction enter the Earth. A compass needle rests freely in its casing so it can maneuver itself. When [...]
Computer Hard Drive Magnets Computer hard drive magnets are indispensable components within modern computing technology. There was once a concern that magnets have the potential to erase data from our hard drives, cause disruptions in computer monitors, or interfere with the electron flow within cables. But these powerful magnets are integral to the functioning of [...]
About Hard Disk Drive Magnets Hard disk drive magnets, also known as disk drive magnets, are primarily used in mechanical hard disks. Regarding them, you may have some knowledge you want to understand. This article compiles six common questions. 1. What material are hard drive magnets made of? The vast majority of magnets from mechanical [...]
About Ndfeb Hexagonal Magnets Hexagonal magnets are considered to be relatively "special-shaped" magnets, belonging to the category of polygonal magnets. Some customers may also refer to them as hexagonal magnets. For customers who are new to this type of magnet, there may be some questions. Below, we have compiled some common questions for your reference. [...]
Nickel Plated Ferrite Disc Magnets The nickel-plated ferrite circular magnet is a magnetic component that uses sintered ferrite circular magnets as the base material and adds a metal coating on its surface. Compared to conventional "bare black ferrite," this product exhibits significant differences in appearance, corrosion resistance, and certain application scenarios. The following picture is [...]
