How do you demagnetize a magnet? Common methods include AC degaussing, heating, a sufficiently strong opposing magnetic field, or controlled industrial pulsing. Steel tools are relatively easy to degauss; high-coercivity neodymium permanent magnets are much harder. Learn what causes irreversible loss, how HcJ, temperature and geometry affect demagnetization, and how to prevent it.Read More

What equipment is used to make neodymium magnets? A sintered NdFeB production line typically includes vacuum melting and strip-casting equipment, hydrogen decrepitation and jet milling, magnetic-field presses, vacuum sintering furnaces, precision grinding, coating, pulse magnetizing and magnetic inspection systems.Read More

Best Practices in Designing a Magnet for Your Application Designing an industrial magnet is a sophisticated process requiring careful consideration of material properties, desired magnetic field strength, shape, environmental factors, and specific functional requirements. With advancements in magnetic materials and manufacturing techniques, magnets are now integral to diverse applications, including electronics, automotive, robotics, renewable energy,...Read More

Magnet pull force usually means magnet-to-steel breakaway force under a defined test setup. It is not a universal safe working load and should not be assumed equal to magnet-to-magnet repulsion. Learn how air gap, steel thickness, surface condition, shear loading, geometry and magnet grade change real force.Read More

Magnets are essential to modern manufacturing because they can hold, move, sense, separate and transmit force across material-handling, automation, motor, sensor, workholding and process applications. Learn how magnetic systems are engineered—and why catalog pull force is not a universal safe working load.Read More

Compare the four main permanent magnet materials: neodymium (NdFeB), ferrite/ceramic, samarium cobalt (SmCo) and Alnico. See which is strongest, lowest cost, most corrosion resistant or best suited to high-temperature service, plus the tradeoffs in size, coercivity, coating, temperature and sourcing.Read More

Magnet Fishing: The Rise of a Unique and Eco-Friendly Hobby Magnet fishing, once a niche activity, has evolved into a popular outdoor hobby, blending treasure hunting, environmentalism, and urban exploration. Armed with powerful magnets and ropes, enthusiasts of this activity scour lakes, rivers, and canals, pulling out all sorts of metal objects, from historical relics...Read More

Choose a magnet by application rather than grade alone. Compare the design priorities for holding and latching, Hall/TMR/AMR sensors, electric motors, magnetic couplings, high-temperature service and corrosive environments, with links to the right calculators, grades, materials, inventory and RFQ tools.Read More

Neodymium magnets are used throughout electronics in Hall/TMR sensors, speakers and headphones, BLDC motors, fans, actuators, hard-disk drives, latches and compact mechanisms. For audio designs, gap flux and Bl—not magnet grade or diameter alone—determine loudspeaker motor performance; NdFeB is especially useful when size and weight must be minimized.Read More
