What are Rare Earth Magnets?

Rare earth magnets, also known as neodymium magnets or samarium cobalt magnets are magnets made from alloys of rare earth elements.  They are currently the strongest type of permanent magnets made, and produce significantly stronger magnetic fields than other types such as ceramic or alnico magnets.  Rare earth magnets have replaced alnico and ferrite magnets in many applications, including head actuators for computer hard disks, magnetic resonance imaging (MRI),loudspeakers and headphones, several types of motors, and more.

Neodymium NdFeB magnets and their application!

At, we sell custom Neodymium NdFeB magnets and custom magnetic assemblies so we can help you find the best fit for your project. Some of the common applications of the rare earth magnets are:

  • Motors and Generators

  • Meters

  • Automotive (clamps, sensors)

  • Aerospace

  • Separation (rods, grids, etc) – 10-12kG (22-26lbs) systems

  • High performance magnetic clamps and pot magnets

  • They are used in computer hard drives.

  • Rare earth magnets also find their utility in high-end speakers.


Our wide selection of neodymium rectangle magnets give you much to choose from. Neodymium bar, block and cube magnets are incredibly powerful for their size, with an approximate pull strength of up to 1760 lbs. Neodymium magnets are the strongest permanent, rare-earth magnets commercially available today with magnetic properties that far exceed other permanent magnet materials. Their high magnetic strength, resistance to demagnetization, low cost and versatility make them the ideal choice for applications ranging from industrial and technical use to personal projects.

Rectangular and Square Neodymium Block Magnets

Most commonly used in manufacturing and engineering industries for their strength and depth of magnetic field, rectangular and square magnets are often used to solve many problems that would otherwise require a very costly solution. Strong rectangular neodymium magnets are widely used during moulding and casting of substances to hold moulds in place this is due to their impressive strength to size ratio.

For caravanning and camping lovers, magnets have many uses including attaching awnings and holding curtains open or shut to name but two (we also find countersunk magnets handy in these scenarios as the holes give you an easier stitch. 

Rare-Earth Neodymium Bar Block Magnets - Rectangular Magnets

Neodymium Block Magnets N35, N42, N45, N50 & N52. No matter how you call this category, strong bar magnets, bar magnets, magnetic blocks, magnet blocks or bar magnets, their basic geometric shape is a rectangle.

Our Quality Rare Earth Neodymium Rectangle Magnets are used in applications such as motor, medical, research, sensor, holding, consumer electronics, consumer products, thin film deposition and automotive. Our wide selection of neodymium rectangle magnets give you much to choose from.

Neodymium block, bar and cube magnets are useful for multiple applications. From creative crafting & DIY projects to exhibition displays, furniture making, packaging, school classroom décor, home and office organizing, medical, science equipment and much more. They are also used for various design & engineering and manufacturing applications where small sized, maximum strength magnets are required.

Our neodymium discs are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). Common finishing options include uncoated, nickel (Ni-Cu-Ni) and gold (Ni-Cu-Ni-Au) plated coatings.

Rare Earth (Neodymium), sometimes called super magnets, are among the most powerful type of permanent magnets available. Neodymium Block Magnets use these Rare Earth Magnets in a cube or rectangular Block Shape. Strong neodymium rare earth block/bar magnets are incredibly powerful for their size and ideal for use in manufacturing, science experiments, woodworking, crafts, DIY and hobby projects.
