Neodymium Cylinder Magnet – 10mm x 10mm | N52

The Neodymium Cylinder Magnet – 10mm x 10mm | N52 is a compact, high-performance rare earth permanent magnet measuring 10mm in diameter x 10mm long. Manufactured from N52 grade Neodymium Iron Boron (NdFeB), this cylindrical magnet combines equal diameter and length dimensions with one of the higher commercially available neodymium magnetic grades, making it suitable for compact engineering, manufacturing, sensor, positioning, product assembly, research and OEM applications.

Its 10mm diameter x 10mm length creates a compact cylindrical profile that can be integrated into appropriately designed round recesses, tubes, housings and mechanical assemblies. N52 identifies the magnetic material grade; it does not by itself specify the finished magnet's pull force, surface Gauss reading or safe working load.

Also known as an N52 neodymium cylinder magnet, rare earth cylinder magnet, NdFeB rod magnet, cylindrical neodymium magnet or 10mm rare earth magnet, this product provides permanent magnetic operation without electricity, batteries or charging.

10mm Diameter x 10mm Long Cylinder Magnet

This neodymium cylinder magnet measures 10mm in diameter x 10mm long, giving it equal diameter and length dimensions.

Its compact cylindrical geometry can be useful for integration into:

• Round recesses
• Cylindrical housings
• Tubes
• Bores
• Product assemblies
• Sensor housings
• Mechanical components
• Prototype devices

The round profile can simplify alignment in products specifically designed around cylindrical magnetic components.

N52 Grade Neodymium Magnet

This magnet is manufactured from N52 grade Neodymium Iron Boron (NdFeB).

N52 is a high-performance neodymium magnetic grade and is commonly selected where strong magnetic properties are required within compact dimensions.

However, the N52 designation should not be interpreted as a pull-force rating.

The finished magnet's practical performance also depends on:

• Magnet dimensions
• Magnetisation direction
• Magnetic circuit
• Target material
• Target steel thickness
• Air gap
• Surface condition
• Installation geometry

N52 also does not directly specify the surface magnetic flux density in Gauss.

Compact High-Performance Rare Earth Magnet

Neodymium magnets are widely used where designers need substantial magnetic performance without using a large magnetic component.

The combination of N52 grade material and compact 10mm x 10mm cylindrical dimensions can make this magnet useful for space-restricted applications involving:

• Magnetic attraction
• Positioning
• Sensing
• Switching
• Alignment
• Product integration
• Magnetic coupling

The suitability of the magnet for a specific application should be determined using the complete magnetic and mechanical requirements of the design.

Sensors and Instrumentation

Cylindrical neodymium magnets are commonly integrated into magnetic sensing systems.

Potential applications include:

• Position detection
• Proximity sensing
• Magnetic switches
• Reed switch activation
• Hall-effect sensor systems
• Instrumentation
• Mechanical position indicators
• Equipment monitoring

Sensor performance depends on factors including magnetic pole orientation, distance from the sensor and the sensitivity of the sensing component.

The magnetisation direction has not been supplied, so this specification should be confirmed before designing a sensor system around this magnet.

Positioning and Alignment

This 10mm x 10mm N52 cylinder magnet can also be incorporated into positioning and alignment systems.

Potential functions include:

• Repeatable component positioning
• Removable components
• Magnetic alignment
• Fixture positioning
• Assembly aids
• Prototype mechanisms
• Product locating systems

Magnetic components should not be relied upon as structural fasteners where mechanical retention is required for safety.

Product Assemblies

The compact cylindrical geometry makes this magnet suitable for incorporation into appropriately designed manufactured products.

Potential uses include:

• Closures
• Removable panels
• Equipment accessories
• Display components
• Mechanical assemblies
• Fixtures
• Electronic products
• Custom housings
• Prototype devices
• OEM products

When integrating the magnet into a product, allow suitable mechanical clearance and avoid force-fitting.

Magnetisation Direction

Cylinder magnets can be manufactured with different magnetisation directions.

A 10mm diameter x 10mm long cylinder magnet may potentially be:

• Axially magnetised through its 10mm length
• Diametrically magnetised across its 10mm diameter
• Manufactured with another application-specific magnetic configuration

The magnetisation direction and pole orientation have not been supplied for this product and should not be assumed from its cylindrical shape.

This is particularly important for:

• Sensors
• Magnetic switches
• Magnet-to-magnet assemblies
• Magnetic couplings
• Positioning systems
• Magnetic circuit design

Confirm the magnetic orientation where field direction is important.

Magnetic Performance

Practical magnetic performance depends on more than the N52 material grade.

Important factors include:

• N52 magnetic material
• Magnet dimensions
• Magnetisation direction
• Magnetic circuit design
• Target steel composition
• Target steel thickness
• Contact area
• Surface flatness
• Air gaps
• Coatings
• Load direction
• Mechanical leverage

No specific pull force or magnetic flux density in Gauss has been supplied for this magnet.

These values should not be inferred from the N52 grade or 10mm x 10mm dimensions alone.

N52 Grade vs Pull Force

The N52 grade describes properties of the neodymium magnetic material, not how many kilograms the finished magnet can hold.

Two N52 magnets can have very different pull forces if they differ in:

• Size
• Shape
• Magnetisation direction
• Contact area
• Magnetic circuit
• Installation conditions

A stated magnetic grade should therefore never be treated as a safe working load.

Direct Pull vs Shear Force

Where this magnet is used against ferromagnetic steel, holding performance can change significantly depending on load direction.

Direct pull occurs when the magnet is separated perpendicular to the target surface.

Shear loading occurs when the magnet is encouraged to slide parallel to the target surface.

Practical shear holding may be substantially lower than direct-pull performance and depends on factors including:

• Surface friction
• Contact area
• Air gaps
• Coatings
• Installation orientation
• Mechanical leverage

Test the completed assembly under realistic conditions where magnetic holding is important.

Air Gaps and Magnetic Attraction

Magnetic attraction generally decreases as the distance between the magnet and its target increases.

Air gaps may be introduced by:

• Paint
• Powder coating
• Adhesive
• Plastic
• Protective films
• Dirt
• Rust
• Product housings
• Mechanical clearance

Even relatively small gaps can noticeably reduce magnetic performance.

For maximum practical attraction, unnecessary separation should generally be minimised.

Target Steel Thickness

The properties of the target steel also influence practical holding performance.

Important factors include:

• Steel composition
• Steel thickness
• Target dimensions
• Surface condition
• Magnetic saturation

Thin steel may not provide the same magnetic performance as a suitable thicker ferromagnetic target.

For important applications, test the magnet against the actual target material.

Bonding a Neodymium Cylinder Magnet

Adhesive bonding can be used to integrate this cylinder magnet into a suitably designed recess or housing.

Before bonding:

• Confirm the required polarity
• Confirm magnetisation direction
• Clean the bonding surfaces
• Remove grease, oil and contamination
• Select an adhesive compatible with the actual magnet surface
• 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 surface finish should be confirmed.

Avoid Force-Fitting

Neodymium Iron Boron is a hard and brittle magnetic material.

Do not attempt to force the magnet into an undersized hole or recess.

Force-fitting can introduce mechanical stress that may cause the magnet to:

• Chip
• Crack
• Fracture
• Break

A suitable housing should provide appropriate clearance and use a compatible retention method.

Do Not Machine Neodymium Magnets

Finished neodymium magnets should not be modified using conventional workshop methods.

Avoid:

• Drilling
• Cutting
• Grinding
• Crushing
• Machining
• Excessive impact

These processes can damage the brittle magnetic material and its surface finish.

Where a different dimension or geometry is required, select a magnet manufactured to the appropriate shape.

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 Cylinder Magnets

Neodymium and ferrite magnets provide different characteristics.

Neodymium cylinder magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties within compact dimensions
• Advantages for space-restricted designs
• Suitability for sensors and precision product assemblies

Ferrite magnets are generally:

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

An N52 neodymium cylinder magnet can therefore be particularly useful where compact dimensions and high magnetic performance relative to size are important.

Permanent Magnetic Operation

This N52 neodymium cylinder 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

Neodymium magnets can attract each other and nearby ferromagnetic objects suddenly and with considerable force.

Handle carefully to avoid:

• Pinched skin
• Trapped fingers
• Magnet collisions
• Chipping
• Cracking
• Fragmentation

Neodymium magnetic material is brittle, so uncontrolled impacts can cause pieces to break away. Appropriate eye protection should be used where fragmentation is possible.

Do not drill, cut, grind, crush or machine neodymium magnets.

Ingestion Hazard

A 10mm x 10mm neodymium magnet presents a serious ingestion hazard.

If multiple magnets are swallowed, or a magnet is swallowed with another metallic object, they can attract through internal tissue and cause severe internal injury.

Keep this magnet securely away from babies and children.

Where incorporated into another product, ensure the magnet is securely retained so it cannot become loose during normal or foreseeable use.

Keep permanent magnets an appropriate distance from:

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