Introducing the New Radial Magnets Technical Resource Hub

Specifying the right magnet is not always as simple as choosing a size and grade. Pull force, operating temperature, coating performance, material selection, air gaps, mounting conditions, and real-world application environments all play an important role in whether a magnet will perform reliably.

That is why Radial Magnets is excited to announce the launch of our new Technical Resource Hub — a free online engineering resource designed to help customers, engineers, purchasing teams, and product developers make better magnet decisions faster.

Built for Real-World Magnet Selection

Magnets are used in thousands of different applications, from sensors and fixtures to motors, assemblies, closures, tools, displays, medical devices, industrial equipment, and consumer products. Each application has its own requirements, and selecting the wrong magnet can lead to weak holding force, coating failure, temperature-related performance loss, or premature product failure.

The Technical Resource Hub was created to simplify that process.

Instead of searching through scattered charts, formulas, and material notes, users can now access several practical magnet selection tools in one place. The hub brings together key technical resources that help answer some of the most common questions customers ask when designing or sourcing magnets.

What You Can Do With the Technical Resource Hub

The new Technical Resource Hub includes several helpful tools for magnet selection and application planning.

Pull Force Calculator

The pull force calculator helps estimate magnet holding force based on magnet geometry, grade, mounting conditions, steel thickness, and air gap. Users can select common magnet shapes such as discs, blocks, and rings, then input dimensions and operating conditions to generate a useful starting estimate.

While real-world pull force can vary depending on steel type, surface finish, flatness, coating, and assembly conditions, this tool gives users a faster way to compare options and narrow down their design requirements.

Grade Comparison Tool

Choosing the right magnet grade is about more than selecting the strongest available option. Higher grades may offer greater magnetic strength, while high-temperature grades may provide better resistance to demagnetization in demanding environments.

The grade comparison section helps users review important magnetic properties such as remanence, intrinsic coercivity, energy product, strength, maximum temperature rating, and typical use cases. This makes it easier to compare materials like N35, N42, N52, high-temperature neodymium grades, and Samarium Cobalt options.

Coating Selector

Magnet coatings are critical for protecting neodymium magnets from corrosion and wear. A magnet used in a dry indoor environment may require a very different coating than one exposed to humidity, washdown, outdoor conditions, or chemical exposure.

The coating selector helps users evaluate coating options based on the application environment, handling conditions, operating temperature, and exposure requirements. This gives customers a better starting point when deciding between coatings such as nickel, epoxy, parylene, and other protective finishes.

Temperature Derating Tool

Temperature is one of the most important factors in magnet performance. As operating temperature increases, magnetic output can temporarily decrease. In some cases, if the magnet is pushed beyond its safe operating range, irreversible loss may occur.

The temperature derating tool helps users visualize how magnetic performance changes with temperature and compare different grades under elevated-temperature conditions. This is especially useful for applications involving motors, sensors, electronics, automotive components, industrial assemblies, and any environment where heat is a concern.

Helping Customers Make Better Decisions Earlier

The goal of the Technical Resource Hub is not to replace engineering review, but to help customers start the conversation with better information.

By using these tools early in the design or sourcing process, customers can:

Reduce trial-and-error during magnet selection
Compare magnet grades more effectively
Understand how air gaps affect pull force
Choose coatings based on real application conditions
Account for temperature before a problem occurs
Identify when a custom magnet may be needed
Communicate requirements more clearly with our team

For purchasing teams, this can also help reduce sourcing delays by making technical requirements easier to define upfront. For engineers, it provides a quick reference point when comparing magnet options during early-stage design.

A Better Starting Point for Custom Magnet Projects

Many applications require magnets that are not available as standard catalog items. The Technical Resource Hub can help users determine whether a stock magnet may work or whether a custom solution is needed.

Radial Magnets manufactures custom neodymium magnets in a wide range of shapes, grades, coatings, tolerances, and magnetization directions. When a project requires a custom magnet, our team can use the information gathered from the Technical Resource Hub to better understand the application and recommend the right next steps.

Free to Use

The Technical Resource Hub is available now and is free to use. Whether you are designing a new product, replacing an existing magnet, comparing grades, evaluating coatings, or trying to understand temperature effects, this tool was built to give you a more informed starting point.

At Radial Magnets, we know magnets. Our goal is to make magnet selection easier, faster, and more reliable for every customer.
