Neodymium rectangle magnets, also known as block magnets or rectangular rare earth magnets, are ideal for mounting, clamping, sensing, and magnetic circuit applications. We stock both neodymium rectangle magnets for high pull force and samarium cobalt rectangle magnets for high-temperature and chemically harsh environments.
Available in a variety of sizes, magnetic grades, and protective coatings to meet your technical requirements.
Common Uses
- Magnetic assemblies & clamping
- Sensors & automation systems
- Motors, pumps & control devices

Frequently Asked Questions
Neodymium rectangle magnets (also called block magnets) are widely used for clamping, holding fixtures, sensors, automation systems, and magnetic circuits. Their high pull force in a compact size makes them ideal when maximum strength is needed in limited space.
Neodymium rectangle magnets provide the highest magnetic strength, making them ideal when maximum pull force is required in compact spaces. Samarium Cobalt (SmCo) rectangle magnets, while not as strong, offer exceptional resistance to high temperatures and corrosion, making them better suited for harsh environments.
Yes. Rectangle magnets distribute force across a flat surface, making them well-suited for mounting, magnetic assemblies, and linear motion systems. Engineers often choose them when even force or compact alignment in assemblies is more important than rotational symmetry.
Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
