Neodymium Disc Magnet – 22mm x 10mm

The Neodymium Disc Magnet – 22mm x 10mm is a powerful rare earth permanent magnet measuring 22mm in diameter x 10mm thick. Manufactured from Neodymium Iron Boron (NdFeB), this compact round magnet provides high magnetic performance relative to its size and is suitable for industrial, manufacturing, engineering, holding, positioning, craft and OEM applications.

Also known as a rare earth disc magnet, round neodymium magnet or NdFeB disc magnet, this 22mm x 10mm magnet can be incorporated into fixtures, assemblies, closures, displays, prototypes and custom magnetic systems. Its cylindrical disc shape provides two broad, flat circular faces, making it particularly convenient for applications requiring compact magnetic components.

As a permanent magnet, the Neodymium Disc Magnet requires no electricity, batteries or charging and provides continuous magnetic attraction throughout normal use.

22mm Diameter x 10mm Thick Disc Magnet

This neodymium magnet measures 22mm in diameter and 10mm thick, providing a substantial disc-shaped magnetic component for applications requiring a compact permanent magnet.

Its simple round geometry can be useful for integration into:

• Circular recesses
• Product housings
• Fixtures
• Equipment
• Displays
• Closures
• Furniture
• Custom manufactured assemblies

The 22mm x 10mm dimensions describe the physical size of the magnet and should not be interpreted as a pull-force or load-capacity rating.

Neodymium Iron Boron Rare Earth Magnet

Neodymium Iron Boron (NdFeB) is a high-performance rare earth magnetic material widely used where strong permanent magnetic performance is required within relatively compact dimensions.

Neodymium magnets are commonly selected for:

• Compact magnetic assemblies
• Industrial fixtures
• Magnetic holding systems
• Sensors
• Equipment
• Product manufacturing
• Engineering applications

The specific NdFeB magnetic grade of this magnet has not been supplied and should not be assumed.

Magnetic Holding and Positioning

The flat circular faces of a disc magnet make this shape suitable for a broad range of magnetic holding and positioning applications.

Potential uses include:

• Removable components
• Magnetic closures
• Locating points
• Fixtures
• Product positioning
• Display components
• Custom magnetic connections

Actual performance depends on the complete magnetic circuit and installation conditions.

Magnetic Holding Performance

The practical holding strength of a neodymium magnet depends on more than its dimensions.

Important factors include:

• Magnetic grade
• Target steel thickness
• Steel composition
• Surface flatness
• Contact area
• Air gaps
• Paint and coatings
• Adhesive layers
• Magnet orientation
• Load direction
• Distance from the target

No specific pull force or Gauss rating has been supplied for this 22mm x 10mm disc magnet, so magnetic performance should not be inferred solely from its dimensions.

Direct Pull vs Shear Force

Magnetic holding performance varies depending on the direction in which the load is applied.

Direct pull occurs when force attempts to separate the magnet perpendicular to the steel surface.

Shear force occurs when the load acts parallel to the surface and encourages the magnet to slide.

Practical vertical holding performance may therefore be considerably lower than ideal direct-pull performance.

This distinction is important when designing magnetic fixtures, closures and mounting systems.

Air Gaps Reduce Magnetic Attraction

Magnetic attraction decreases rapidly as the distance between a magnet and its ferromagnetic target increases.

Even thin layers can reduce performance, including:

• Paint
• Adhesive
• Plastic
• Paper
• Fabric
• Protective coatings
• Dirt
• Surface irregularities

For strongest practical attraction, maximise direct contact with clean, flat and sufficiently thick ferromagnetic steel.

Bonding Neodymium Disc Magnets

The flat surfaces of this disc magnet make it suitable for bonding into compatible products and assemblies.

Potential bonded applications include:

• Furniture
• Cabinetry
• Displays
• Signage
• Closures
• Product housings
• Fixtures
• Custom manufactured components

Before bonding, ensure the magnet and substrate are clean and use an adhesive compatible with both surfaces.

Follow the adhesive manufacturer's preparation and curing instructions.

Compatible Target Materials

Neodymium magnets strongly attract suitable ferromagnetic iron and steel.

Compatible target materials may include:

• Mild steel
• Iron
• Magnetic steel sheet
• Ferromagnetic machinery components
• Compatible steel brackets and plates

The magnet will not effectively attract:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide weak or negligible magnetic attraction and should be tested before use.

Permanent Magnetic Operation

This NdFeB disc is a permanent magnet, requiring no external power source to maintain its magnetic field.

It requires:

• No electricity
• No batteries
• No charging
• No electrical wiring

The magnetic field remains continuously active.

Neodymium vs Ferrite Disc Magnets

Both neodymium and ferrite are common permanent magnetic materials, but their characteristics differ.

Neodymium magnets generally offer:

• Much higher magnetic performance relative to size
• More compact designs for high-strength applications
• Strong attraction from relatively small magnet volumes

Ferrite magnets are generally:

• More economical
• Naturally corrosion resistant
• Less powerful relative to their physical size
• Suitable for many general-purpose applications

Neodymium is typically selected when higher magnetic performance is required within limited space.

Industrial and OEM Applications

The combination of compact dimensions and rare earth magnetic material makes this 22mm x 10mm disc magnet suitable for integration into a wide range of manufactured products.

Potential users include:

• Equipment manufacturers
• Machinery builders
• Engineers
• Fabricators
• Furniture manufacturers
• Display manufacturers
• Product designers

For engineered applications, the magnet should be assessed as part of the complete magnetic circuit and mechanical assembly.

Handling Neodymium Magnets

Neodymium magnets can generate strong attraction forces and should be handled carefully.

NdFeB magnetic material is also hard and brittle. Magnets can chip, crack or fracture if they:

• Snap forcefully together
• Strike a steel surface
• Are dropped
• Experience excessive mechanical stress

Do not drill, cut or machine neodymium magnets using conventional methods.

When separating strong magnets, slide them apart carefully rather than allowing uncontrolled collisions.

Please Note

This product is a Neodymium Disc Magnet measuring 22mm in diameter x 10mm thick.

No specific NdFeB magnetic grade, coating or plating, pull force, Gauss rating, magnetisation direction, dimensional tolerance or maximum operating temperature has been supplied and these specifications should not be assumed.

Actual magnetic performance depends on magnetic grade, target steel thickness and composition, contact area, surface condition, air gaps, coatings, load direction and magnet orientation.

Neodymium magnetic material is inherently brittle and can chip or fracture under impact. Avoid drilling, cutting, machining or allowing magnets to collide uncontrollably.

Strong neodymium magnets can create serious pinch hazards. Keep them away from children, pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
