5mm Diameter x 10mm Long Cylinder Magnet

This N50 neodymium cylinder magnet measures 5mm in diameter x 10mm long.

Its 10mm length is twice its 5mm diameter, creating a compact rod-like geometry that can be useful for installation in:

• Cylindrical recesses
• Tubes
• Housings
• Small mechanical components
• Sensor assemblies
• Electronic devices
• Prototype mechanisms

The dimensions describe the physical geometry of the magnet and do not indicate its pull force or holding capacity.

N50 Grade Neodymium

This cylinder magnet is manufactured from N50 grade Neodymium Iron Boron, a high-performance rare earth magnetic material.

N50 offers high magnetic energy density, allowing substantial magnetic performance to be produced from relatively compact magnet dimensions.

This makes N50 particularly useful where:

• Available space is limited
• Small magnet dimensions are required
• High magnetic performance relative to size is desirable
• A compact permanent magnetic source is needed
• Miniaturisation is important to the product design

What Does N50 Mean?

N50 is the magnetic grade of the Neodymium Iron Boron material.

The numerical designation relates to the material's maximum energy product and is used to differentiate the magnetic performance potential of different NdFeB grades.

The N50 designation does not mean this magnet has a 50kg pull force.

N50 also does not directly specify:

• Surface Gauss
• Holding capacity
• Safe working load
• Magnetisation direction
• Pole orientation
• Maximum operating temperature

These characteristics depend on the finished magnet and its application.

High Magnetic Performance in a Compact Format

Neodymium magnets are widely used where strong magnetic performance is required from limited physical space.

At only 5mm diameter x 10mm long, this N50 cylinder can be integrated into compact components where larger magnetic materials may be impractical.

Potential functions include:

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

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

Sensors and Instrumentation

The compact cylindrical format can be particularly useful in sensor and instrumentation applications.

Potential uses include:

• Hall-effect sensors
• Reed switches
• Position sensors
• Proximity detection
• Magnetic switching
• Rotation or movement detection
• Equipment monitoring

Sensor response depends on the magnet's magnetisation direction, pole orientation, distance from the sensor, sensor sensitivity and surrounding materials.

The magnetisation direction of this product has not been supplied and should be confirmed where magnetic field orientation is critical.

Positioning and Alignment

This N50 cylinder magnet can be incorporated into compact magnetic positioning systems.

Potential applications include:

• Component locating
• Repeatable positioning
• Magnetic alignment
• Assembly aids
• Fixtures and jigs
• Detachable components
• Prototype mechanisms

Where two or more magnets are used together, confirm polarity before permanent installation.

Magnetisation Direction

Cylinder magnets can be manufactured with different magnetisation configurations.

A 5mm diameter x 10mm long cylinder magnet could potentially be:

• Axially magnetised along its 10mm length
• Diametrically magnetised across its 5mm diameter
• Manufactured with another specialised configuration

The actual magnetisation direction and pole configuration have not been supplied and should not be assumed from the cylindrical shape.

Confirm this specification where pole position or magnetic field direction is important.

Magnetic Performance

Although this magnet is confirmed as N50 grade, practical magnetic performance depends on factors including:

• N50 material properties
• Magnetisation direction
• Pole configuration
• Magnetic circuit design
• Target material
• Target steel thickness
• Available contact area
• Surface condition
• Air gaps
• Load direction
• Installation geometry

No specific pull force or magnetic flux density in Gauss has been supplied and these values should not be estimated from the N50 grade alone.

Direct Pull vs Shear

Magnetic holding performance varies according to the direction of the applied load.

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 surface.

Shear performance can be affected by:

• Surface friction
• Surface finish
• Installation orientation
• Air gaps
• Vibration
• Mechanical leverage

Testing under realistic installation conditions is recommended where holding performance is important.

Air Gaps and Magnetic Attraction

Even small air gaps can reduce magnetic attraction.

Potential sources include:

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

This is particularly relevant for a compact 5mm diameter magnet, as relatively small gaps can represent a significant proportion of the magnet's dimensions.

Where strong magnetic interaction is required, unnecessary separation should be minimised.

Target Steel Thickness

When this magnet operates against ferromagnetic steel, the target forms part of the magnetic circuit.

Performance can vary depending on:

• Steel composition
• Steel thickness
• Target dimensions
• Contact area
• Surface condition

Very thin steel may not provide the same magnetic response as a suitably thick ferromagnetic target.

For performance-critical applications, test the magnet against the actual target material.

Bonding the Magnet

Adhesive bonding is one method of incorporating this cylinder magnet into a product or assembly.

Before bonding:

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

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

Avoid Force-Fitting

Neodymium Iron Boron is hard but brittle.

Do not force this magnet into an undersized hole or recess.

Force-fitting can result in:

• Chipping
• Cracking
• Fracturing
• Surface coating damage

Provide suitable mechanical clearance and use an appropriate retention method.

Because this cylinder has a relatively slender 2:1 profile, avoid excessive bending, side loading or leverage during installation.

Do Not Machine Neodymium Magnets

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

Avoid:

• Drilling
• Cutting
• Grinding
• Crushing
• Filing
• Machining

These processes can fracture the brittle magnetic material and damage any protective surface coating.

Select a magnet manufactured to the required dimensions instead.

Compatible Target Materials

Neodymium magnets attract suitable ferromagnetic materials, including:

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

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

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

Many stainless steel grades can also be weakly magnetic or non-magnetic.

Test the intended target where magnetic compatibility is important.

N50 Neodymium vs Ferrite Magnets

N50 neodymium provides much higher magnetic energy density than conventional ferrite material.

N50 neodymium is particularly useful for:

• Compact assemblies
• Space-constrained designs
• Sensors
• Electronics
• Precision mechanisms
• High magnetic performance relative to size

Ferrite magnets may be preferred for:

• More economical applications
• Larger magnetic components
• Applications benefiting from good natural corrosion resistance
• Situations where lower magnetic strength relative to size is acceptable

For compact components such as this 5mm x 10mm cylinder, neodymium provides significant advantages where magnetic performance and size are important.

Permanent Magnetic Operation

This N50 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

This 5mm x 10mm neodymium cylinder magnet is small enough to present a serious ingestion hazard.

Keep this magnet securely away from babies and children.

If multiple magnets are swallowed, they can attract to each other through body tissue and cause severe internal injury. Suspected magnet ingestion requires urgent medical attention.

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

Neodymium magnets can also attract rapidly to other magnets and ferromagnetic objects. Avoid uncontrolled collisions, which can cause the brittle magnetic material to chip or fracture.

Keep permanent magnets an appropriate distance from:

• Pacemakers and implanted medical devices
• Magnetic cards
• Magnetic storage media
• Magnetically sensitive instruments
• Sensitive electronic equipment

Please Note

This product is an N50 Neodymium Cylinder Magnet measuring 5mm in diameter x 10mm long, manufactured from Neodymium Iron Boron (NdFeB) rare earth magnetic material.

The N50 designation identifies the magnetic material grade and does not mean the magnet has a 50kg pull force.

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

Actual magnetic performance depends on the N50 material properties, magnetisation configuration, magnetic circuit, target material, target steel thickness, available contact area, surface condition, air gaps, load direction and installation geometry.

Neodymium is a hard and brittle magnetic material. Avoid impact, excessive side loading, force-fitting, drilling, cutting, grinding or machining.

Due to its small size, this magnet presents a serious ingestion hazard and must be kept securely away from babies and children.

The stated 5mm diameter x 10mm length describes the physical dimensions of the magnet and does not represent its pull force, holding capacity or safe working load.

This magnet is not certified lifting equipment and should not be used for overhead or safety-critical lifting.
