Neodymium Magnet Information

Magnets play a critical but often overlooked role in modern dental care. Compact neodymium magnets have become essential components in both clinical and laboratory settings as dental treatments become more precise and patient-friendly. Their small size, predictable holding force, and reliability make them well-suited for applications where space, comfort, and performance must align. Among the most commonly used formats are...

When engineers need a magnet that can withstand heat, corrosion, vibration, and demanding operational environments, two materials typically top the shortlist: samarium-cobalt (SmCo) and high-temperature neodymium (NdFeB). Both are rare-earth magnets, but their performance characteristics differ in essential ways.  Samarium cobalt offers exceptional temperature stability (up to 350°C+), inherent corrosion resistance, and long-term magnetic reliability. It’s the preferred choice for...

At Apex Magnets, we help businesses navigate the evolving supply chain for neodymium, samarium-cobalt, and other advanced magnetic materials. Here’s what...

As the year comes to a close, many business leaders take time to review performance, reforecast budgets, and prepare for what’s ahead. However, in today’s unpredictable business climate, preparation involves building flexibility, evaluating supplier relationships, and planning strategically for potential disruptions. If you rely on neodymium magnets, here are ways your business can enter the new year with confidence. 1...

Neodymium magnets are among the strongest permanent magnets available, powering a wide range of applications, from electric motors to small devices. But you’ll notice they come in so many shapes and styles — discs, blocks, rings, countersunk, spheres, and more. Why so many? Because the shape and style of a magnet affect its functionality. Selecting the wrong type or improperly...

Magnets are everywhere, from the fridge door to your headphones, but have you ever wondered why certain materials are magnetic while others are not? The answer lies in the structure of atoms and the behavior of their electrons. The Science Behind Magnetism Atoms are made up of protons, neutrons, and electrons. Electrons orbit the nucleus and also “spin.” These tiny...

Magnets are essential tools across industries, from medical device manufacturing to retail display solutions. But when it comes to sourcing or evaluating magnets for your business, one of the most common questions is: How do you measure the strength of a magnet? Understanding this helps ensure you select the right magnet for performance, safety, and efficiency in your operations. Tools...

Permanent magnets in aircraft navigation and control systems support a range of critical technologies, from angle sensing and feedback loops to electric actuators and stabilization systems. Their ability to deliver contactless, wear-resistant, and power-independent magnetic fields makes them a smart choice for environments that demand long life, reliability, and weight efficiency. Here’s how and where permanent magnets are supporting aviation’s...

While most magnets are magnetized through their length or thickness, diametric magnets are magnetized across their diameter or width, as in diametric blocks. This creates a distinct magnetic field pattern that opens up new possibilities for industrial applications. If you need more help visualizing the difference, view our helpful video about axial vs. diametric magnets here. If you’re working on...
