Overview - Neodymium NdFeB Block Magnets

Neodymium (rare earth) NdFeB block magnets

Neodymium block magnets are high-strength permanent magnets manufactured from neodymium-iron-boron (NdFeB), the most powerful commercially available magnetic material. These block magnets deliver exceptional magnetic force in a compact form, making them ideal for applications where maximum holding power, precise magnetic positioning, and reliability are essential.

The rectangular block shape provides a uniform magnetic field across flat surfaces, enabling consistent performance for magnetic clamping, fixturing, sensors, magnetic separation, and tooling applications. Neodymium block magnets combine high magnetic energy with dimensional versatility, making them a versatile choice for engineers, designers, technicians, and hobbyists.

Neodymium magnets are characterised by high coercivity and energy product, allowing them to maintain strong magnetic performance even in demanding environments. To enhance durability and corrosion resistance, these magnets are typically supplied with protective finishes that help withstand everyday wear and environmental exposure.


Typical Applications

Neodymium Block Magnets are commonly used for:

  • Holding and positioning ferrous components on flat surfaces

  • Magnetic clamping and workholding in fabrication and assembly

  • Sensor mounting and alignment

  • Magnetic separation and retrieval tasks

  • Prototyping, DIY, and maker projects requiring powerful magnets

Their strong magnetic performance and compact size make them suitable for use in workshops, laboratories, industrial settings, and consumer projects.


Why Choose Neodymium Block Magnets

Neodymium block magnets deliver outstanding magnetic strength relative to size, enabling them to outperform many other permanent magnet types in holding force and magnetic field intensity. Their block geometry supports consistent magnetic attraction over broad surface areas, and their reliable magnetic performance makes them a practical choice across technical, industrial, and creative applications.


Key Benefits

  • Exceptional magnetic strength – highest performance among permanent magnets

  • Compact and versatile – powerful hold in a small form factor

  • Uniform magnetic field – steady attraction on flat surfaces

  • Durable with protective finish – enhanced corrosion resistance

  • Wide range of applications – from industrial workholding to DIY projects

"We were delighted with the service provided by Eclipse Magnetics; from the initial site survey through to delivery."

Adrian Seeley, Production Supervisor at AB MAURI UK & Ireland

"I cannot begin to tell you how much it has helped our operation, the magnetic filtration unit has been a real problem solver it has surpassed all our expectations. Its cured a 30 year plague!"

Maintenance Manager at EXL Tube (Steel Ventures)

"This technology is economical, reliable and efficient. I believe that magnetic filtration technology is the future."

John Smith, MMTCI

"Magnetic filtration has dramatically cleaned up our fluids and improved the surface finish we can offer. It extracts around 50Kg per day of ferrous waste."

Facilities Manager, Milacron Machines (Sub-Contract Machining)

"We chose Eclipse Magnetics to supply our housed grid because they are a respected and well-established brand. They offered us a very competitive price, and the process of ordering and installation was straightforward and reliable."

Pat Richards, Chief Engineer at Simpsons Malt

“We are delighted with the Automag installation; it’s solved all the problems we were having previously with downtime and maintenance costs. The filter means that we are able to use recycled water, which is saving us £1000 per week!”

Kenneth McRae, Principle Engineer at Vallourec

"Here at Qualflow, we base our business on a philosophy of make the product simple to use, reliable and cost-effective. Eclipse Magnetics’ neodymium magnets offer the strongest magnetic performance, and are nickel plated, making them a cost effective.."

Justin Lawler Ph.D. MBA, Chief Technology Officer at Qualflow Systems Ltd

"The Ultralift Plus magnetic lifter from Eclipse Magnetics is the perfect solution for the pick-up and transportation of the ultrasonic calibration blocks in our facility"

John Crossley, NDT Technology Lead at the Nuclear AMRC

"The result is an aesthetically pleasing system, which is effective in trapping metal contaminants and is easy to clean..."
