Neodymium Disc Magnet – 50mm x 6mm

The Neodymium Disc Magnet – 50mm x 6mm is a large, low-profile rare earth permanent magnet measuring 50mm in diameter x 6mm thick. Manufactured from Neodymium Iron Boron (NdFeB), this circular magnet combines a broad 50mm face with a relatively slim 6mm profile, making it suitable for industrial equipment, engineering, manufacturing, fixtures and jigs, product assemblies, magnetic closures, displays, furniture, research, prototypes and custom OEM applications.

Neodymium magnets are known for providing high magnetic performance relative to their physical size. The broad circular geometry of this magnet can be useful where a larger magnetic surface is required but installation depth is limited.

Also known as a 50mm neodymium disc magnet, rare earth round magnet, NdFeB disc magnet, flat neodymium magnet or circular rare earth magnet, it provides permanent magnetic operation without electricity, batteries or charging.

50mm Diameter x 6mm Thick Disc Magnet

This neodymium disc magnet measures 50mm in diameter x 6mm thick, providing a wide circular face combined with a relatively shallow profile.

This geometry can be useful for applications requiring a larger-diameter magnet without the installation depth of a thicker cylindrical magnet.

Potential installations include:

• Shallow circular recesses
• Flat product assemblies
• Equipment housings
• Magnetic fixtures
• Display systems
• Furniture components
• Removable panels
• Custom manufactured products

Where the magnet is installed into a recess, provide appropriate dimensional clearance rather than force-fitting the brittle neodymium material.

Neodymium Iron Boron Rare Earth Magnet

This disc magnet is manufactured from Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material.

Neodymium magnets are widely used where substantial magnetic performance is required from relatively compact dimensions.

Common uses include:

• Holding
• Positioning
• Magnetic closures
• Product integration
• Fixtures and jigs
• Mechanical assemblies
• Sensors and equipment
• Research and development

The specific neodymium magnetic grade has not been supplied for this product and should not be assumed.

Large, Low-Profile Magnetic Design

The combination of a 50mm diameter and 6mm thickness gives this magnet a broad, flat geometry.

This can be useful where:

• Installation depth is restricted
• A broad circular magnetic component is preferred
• The magnet needs to fit into a shallow recess
• A low-profile magnetic closure is required
• Magnetic attraction needs to be distributed across a relatively large face

The magnet's dimensions alone do not determine its holding force. Magnetic grade, magnetisation, target material and installation conditions also affect practical performance.

Fixtures, Jigs and Positioning

Large neodymium disc magnets can be incorporated into appropriately designed fixtures, jigs and positioning systems.

Potential applications include:

• Component positioning
• Removable fixtures
• Assembly aids
• Manufacturing equipment
• Inspection fixtures
• Prototype tooling
• Custom workholding systems

Where unexpected magnetic release could create a hazard, use suitable mechanical or secondary retention rather than relying solely on magnetic attraction.

Magnetic Closures and Removable Panels

The low-profile circular format can also be useful for magnetic closure and removable-panel systems.

Potential applications include:

• Access panels
• Furniture components
• Displays
• Equipment covers
• Removable housings
• Custom enclosures
• Exhibition equipment

The magnet may attract compatible ferromagnetic steel or interact with another appropriately oriented permanent magnet.

For magnet-to-magnet applications, confirm polarity and magnetisation orientation before permanently installing the magnets.

Magnetisation Direction

Disc magnets can be manufactured with different magnetisation configurations.

A disc magnet may, for example, be magnetised through its thickness, across its diameter or in another application-specific configuration.

The magnetisation direction and pole orientation have not been supplied for this 50mm x 6mm neodymium disc magnet and should not be assumed.

This specification should be confirmed where magnetic field orientation is important, including:

• Magnet-to-magnet assemblies
• Sensors
• Magnetic switching
• Engineered magnetic circuits
• Specialised positioning systems

Magnetic Performance

The practical magnetic performance of this 50mm x 6mm neodymium disc depends on factors including:

• Neodymium grade
• Magnetisation direction
• Magnet geometry
• Magnetic circuit design
• Target steel composition
• Target steel thickness
• Available contact area
• Surface condition
• Air gaps
• Paint and coatings
• Load direction
• Mechanical leverage

No specific pull force or magnetic flux density in Gauss has been supplied and these values should not be inferred from the dimensions alone.

Pull Force vs Safe Working Load

A magnet's pull force, where specified, is normally determined under particular test conditions and should not automatically be interpreted as the weight that can safely be suspended or lifted in a real-world application.

Practical holding can be reduced by:

• Thin steel
• Painted surfaces
• Rust
• Dirt
• Curved surfaces
• Air gaps
• Side loading
• Vibration
• Mechanical leverage
• Incomplete contact

No pull-force specification has been supplied for this magnet.

It should not be assigned a lifting capacity or safe working load based solely on its 50mm diameter or neodymium construction.

Direct Pull vs Shear Force

Magnetic holding performance can vary significantly according to the direction of the applied load.

Direct pull occurs when the magnet is separated perpendicular to a compatible steel surface.

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

Practical shear holding can be substantially lower than direct-pull performance and is influenced by:

• Surface friction
• Installation orientation
• Contact area
• Surface coatings
• Mechanical leverage
• Vibration

Test the magnet in the actual application where holding performance is important.

Air Gaps and Surface Contact

Neodymium magnets generally provide their strongest practical attraction when positioned close to clean, flat ferromagnetic material.

Magnetic performance can be reduced by gaps created by:

• Paint
• Powder coating
• Adhesive
• Plastic
• Protective films
• Dirt
• Rust
• Uneven surfaces
• Mechanical clearance

For best practical magnetic performance, minimise unnecessary separation between the magnet and target steel wherever the application allows.

Target Steel Thickness

The properties of the target steel can have a significant effect on magnetic holding.

A large-diameter magnet does not necessarily achieve its potential magnetic performance when attached to very thin steel.

Performance can depend on:

• Steel thickness
• Steel composition
• Size of the steel component
• Surface flatness
• Magnetic saturation
• Coatings and air gaps

Where magnetic holding is important, test the magnet using the actual steel component intended for the application.

Bonding a Neodymium Disc Magnet

This 50mm x 6mm disc magnet may be bonded into an appropriately designed recess, housing or product assembly.

Before bonding:

• Confirm polarity and required magnetic orientation
• Clean the bonding surfaces
• Remove oil, grease and contamination
• Select an adhesive compatible with the magnet's actual surface finish
• Provide appropriate dimensional clearance
• Avoid force-fitting
• Allow the adhesive to cure according to its instructions

The specific coating or plating has not been supplied, so adhesive compatibility with the actual magnet surface should be confirmed before permanent assembly.

Avoid Bending and Mechanical Leverage

Although neodymium magnets provide strong magnetic properties, the magnetic material itself is hard and brittle.

This is particularly important for a relatively thin 50mm x 6mm disc, as mechanical leverage or bending loads across the broad diameter can damage the magnet.

Avoid:

• Bending the magnet
• Using it as a structural component
• Prying it from a surface using excessive leverage
• Force-fitting it into a recess
• Allowing magnets to collide
• Dropping it onto hard surfaces
• Applying concentrated impact loads

Where possible, remove a large disc magnet using a controlled sliding or appropriately designed separation method rather than bending or levering the magnet.

Compatible Target Materials

Neodymium magnets attract suitable ferromagnetic materials, including:

• Mild steel
• Iron
• Magnetic steel
• Compatible ferromagnetic components

They will not effectively attract inherently non-magnetic materials such as:

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

Many stainless steel grades may also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attraction.

Neodymium vs Ferrite Disc Magnets

Neodymium and ferrite magnets provide different characteristics.

Neodymium disc magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties from compact dimensions
• Advantages where installation space is restricted
• Broad suitability for engineering and manufactured products

Ferrite disc magnets are generally:

• More economical
• Naturally corrosion resistant
• Resistant to demagnetisation
• Suitable for many general-purpose applications
• Often physically larger where comparable magnetic performance is required

Neodymium can therefore be particularly useful where a strong permanent magnetic material is required within a relatively compact installation space.

Permanent Magnetic Operation

This neodymium disc magnet is a permanent magnet.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

Its magnetic field remains continuously active during normal use.

Safety and Handling

A 50mm diameter neodymium magnet can attract other magnets and ferromagnetic objects suddenly and with significant force.

Keep fingers and skin clear of the space between the magnet and nearby steel or other magnets to reduce the risk of pinching or crushing injuries.

Neodymium magnetic material is brittle and can chip, crack or fragment if magnets collide or strike a hard surface.

Do not:

• Drill
• Cut
• Grind
• Machine
• Bend
• Crush
• Force-fit the magnet

Keep neodymium magnets away from babies and children and maintain an appropriate distance from:

• Pacemakers
• Implanted medical devices
• Magnetic storage media
• Magnetic cards
• Sensitive electronic equipment

Use particular care when separating multiple large neodymium magnets. Slide magnets apart in a controlled manner where appropriate rather than attempting to pull them directly apart with fingers positioned between magnetic surfaces.
