Neodymium Iron Boron Rare Earth Magnet

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

Neodymium magnets are widely used in engineered and manufactured products where strong magnetic properties are required from compact dimensions.

Typical applications include:

• Magnetic sensing
• Positioning
• Holding
• Product integration
• Mechanical assemblies
• Instrumentation
• Research equipment
• Prototype devices

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

Compact Rod-Style Magnet

The 6.35mm x 12.7mm dimensions provide a cylindrical profile suitable for applications where a compact magnetic rod is preferable to a thin disc or rectangular block.

Potential uses include:

• Deep circular recesses
• Sensor actuation
• Mechanical positioning
• Magnetic catches
• Tubular components
• Custom magnetic mechanisms
• Precision product assemblies

Where the magnet is incorporated into a mechanical component, the surrounding design should protect the brittle neodymium material from excessive impact and mechanical stress.

Sensors and Instrumentation

Compact cylinder magnets can be incorporated into appropriately designed magnetic sensing systems.

Potential applications include:

• Reed switch activation
• Hall-effect sensing
• Position detection
• Proximity sensing
• Magnetic switching
• Instrumentation
• Automation
• Electronic prototypes

The magnetisation direction and pole orientation have not been supplied for this product.

Where the position or direction of the magnetic field is critical to sensor operation, confirm the required magnetisation specification before installation.

Product Assemblies and Engineering

The compact cylindrical shape can make this magnet suitable for integration into manufactured products and custom engineering assemblies.

Potential applications include:

• Removable components
• Magnetic positioning mechanisms
• Small catches
• Equipment housings
• Mechanical assemblies
• Fixtures
• Prototype devices
• Instrumentation
• OEM products

Depending on the application, the magnet may attract compatible ferromagnetic steel or interact with another appropriately oriented permanent magnet.

Magnetisation Direction

Cylinder magnets can be manufactured with different magnetisation configurations.

Depending on the product design, a cylinder magnet may be magnetised:

• Axially along its length
• Diametrically across its diameter
• In another application-specific configuration

The magnetisation direction of this 6.35mm x 12.7mm cylinder magnet has not been supplied and should not be assumed.

This is particularly important for:

• Hall-effect sensors
• Reed switches
• Magnetic encoders
• Magnet-to-magnet assemblies
• Engineered magnetic circuits

Confirm magnetisation direction and polarity before permanently installing the magnet where field orientation is important.

Magnetic Performance

Actual magnetic performance 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 for this magnet and these values should not be inferred from its dimensions alone.

Direct Pull vs Shear Force

Magnetic holding performance varies according to the direction in which a load is applied.

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

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

Practical shear holding can be considerably lower than direct-pull performance and depends heavily on:

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

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

Air Gaps and Magnetic Performance

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

Minimising unnecessary separation between the magnet and target material can improve practical magnetic performance.

Bonding a Neodymium Cylinder Magnet

This 6.35mm x 12.7mm cylinder magnet may be bonded into an appropriately sized recess or housing.

Before bonding:

• Confirm polarity and magnetisation orientation
• 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 magnet's actual surface finish should be confirmed.

Avoid Force-Fitting Neodymium Magnets

Neodymium magnets are hard and brittle and should not be pressed forcefully into an undersized recess.

Force-fitting may cause the magnet to:

• Chip
• Crack
• Fracture
• Damage its surface finish

Where possible, use a correctly sized recess with appropriate clearance and a suitable bonding method.

Compatible Target Materials

Neodymium magnets attract suitable ferromagnetic materials, including:

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

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

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

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

Neodymium vs Ferrite Cylinder Magnets

Neodymium and ferrite magnets offer different characteristics.

Neodymium cylinder magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties from compact dimensions
• Advantages for space-constrained applications
• Broad suitability for sensors, engineering and precision assemblies

Ferrite magnets are generally:

• More economical
• Naturally corrosion resistant
• Suitable for many general-purpose applications
• Often used where larger physical dimensions are acceptable

Neodymium is particularly useful where a compact magnetic component is required and available installation space is limited.

Permanent Magnetic Operation

This 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.
