Magnets in medical devices are used for sensors, miniature motors and pumps, magnetic couplings, actuators, encoders, retention and non-contact positioning. Learn how to specify material, grade, field at the working gap, magnetization direction, coating, temperature, tolerances, traceability and compliance for OEM medical-device applications.Read More

Can you cut, drill or grind a neodymium magnet? Usually, you should not modify a finished magnet. Brittle magnet material can crack or chip, machining heat can cause irreversible magnetic loss, protective coatings can be damaged, and NdFeB dust can be combustible. Learn safer alternatives, including stock sizes and custom pre-machined magnets.Read More

Radial vs. diametric magnetization explained: diametric magnets place north and south poles on opposite sides of the curved surface; true radial ring magnets follow the local radius around the circumference; axial magnets place poles on the flat faces; and multipole rings use several alternating poles. Compare sensor, encoder, motor and custom ring applications.Read More

Predictions for 2025 in the Magnetics Industry The magnetics industry is at the forefront of technological innovation, serving as a critical enabler for renewable energy, electric vehicles (EVs), advanced electronics, and more. As we enter 2025, several transformative trends are shaping the future of this dynamic sector. 1. Expansion of Rare Earth Alternatives The dependency...Read More

What metals are not magnetic? Aluminum, copper, brass, gold, silver, lead and titanium do not strongly stick to ordinary magnets. Learn why aluminum is only weakly paramagnetic, why copper and precious metals are diamagnetic, how 304/316 stainless steel behaves, and why non-magnetic target materials matter in real magnetic assemblies.Read More

What is gauss? Gauss (G) measures magnetic flux density at a specific point. 1 gauss = 0.0001 tesla = 0.1 millitesla, and 10,000 gauss = 1 tesla. Learn surface gauss, gaussmeter measurement, field at distance, and why gauss is not the same as pull force or magnet grade.Read More

Sensor magnets for Hall-effect, TMR, AMR and rotary position sensing should be selected by magnetic field at the sensor location, air gap, polarity, magnetization direction, temperature and tolerance—not pull force alone. Compare stock sensor magnets, field-at-distance tools and custom OEM options.Read More

How do maglev trains work? Learn how magnetic levitation, guidance and linear-motor propulsion work, compare EMS vs. EDS systems, and see where electromagnets, superconducting magnets and Halbach arrays fit.Read More
