Neodymium Magnet Information

Permanent magnets are built for strength, but the right coating helps them stay that way. While a coating doesn't make a magnet stronger, it plays an important role in protecting the magnet from corrosion, moisture, chemicals, and everyday wear. Choosing the right coating can extend the life of your magnet and improve its performance in your specific application. Why Do...

Choosing the Right Method for Bridge & Structure Sensors Structural health monitoring (SHM) has moved from a research novelty to a standard part of managing aging infrastructure. Accelerometers, strain gauges, tilt sensors, and vibration monitors are now routinely deployed on bridges, towers, parking structures, and industrial steel frames — often on assets that can't afford downtime, permitting delays, or coating...

You found the magnet. You placed it exactly where you wanted it. You stepped back… …and it slid down the wall. Or maybe it didn’t stick at all. If you’ve ever thought, “Why isn’t my magnet working?” you’re definitely not alone. It’s one of the most common questions we hear at Apex Magnets, and thankfully, the answer is usually simple...

In industrial and commercial applications, some of the most important magnets are the ones you barely notice. Tiny neodymium magnets, often measuring just a few millimeters, are used in everything from product design and cabinetry to electronics, medical devices, and specialty manufacturing. Despite their compact size, these magnets can deliver impressive holding strength and precision performance. The Significance of Miniature...

Magnets come in a wide range of sizes, materials, grades, and strengths. Many factors determine magnet strength, including shape, size, coating, pull force, and the environmental conditions in which the magnet is used. Understanding how magnet strength is measured based on these factors can help you select the right magnet for your application. Understanding Magnet Grades and N Ratings The...

It’s natural for procurement teams and engineers to look for ways to reduce component costs, especially on parts that appear simple at first glance. Magnets often fall into that category. Often choosing a cheap magnet seems like a great way to reduce costs. But in practice, what looks like a small savings upfront can lead to performance issues, rework, and...

Neodymium extraction in electronics recycling focuses on reclaiming valuable materials from end-of-life devices. While the concept is straightforward—recover and reuse rare earth elements—the process itself involves technical, economic, and logistical challenges. Where Neodymium Is Found in Electronics Neodymium magnets are widely used in modern electronic devices because of their strength and compact size. They are commonly found in: hard disk...

Rubber coated magnets combine a strong internal magnet with a protective outer layer of rubber. The rubber coating protects the magnet from corrosion and prevents damage to the surface it contacts, making these magnets particularly useful when you need grip, durability, and surface protection. Common uses of rubber coated magnets include automotive, industrial, and consumer environments where magnets may come...

Apex Technical Guide: Optimizing Magnets in High-Humidity and Transitional Climates

The prototyping phase is the most critical stage of any engineering project. Whether you are developing a new medical device or a high-speed robotics assembly, the magnets you choose can determine the success of your proof-of-concept. When ordering magnets for prototyping, a "one size fits all" approach often leads to costly delays. To ensure your R&D remains on schedule and...
