N35 Grade Neodymium Magnet

This cylinder magnet is manufactured from N35 grade Neodymium Iron Boron.

N35 is a widely used neodymium magnetic grade that provides strong permanent magnetic properties relative to its physical size.

N35 magnets are commonly selected where:

• Compact magnetic dimensions are required
• Strong permanent magnetism is needed
• Available installation space is limited
• A reliable rare earth magnetic material is preferred
• Magnetic performance needs to exceed that typically available from similarly sized ferrite magnets

The N35 designation identifies the magnetic material grade. It does not mean this magnet has a 35kg pull force.

What Does N35 Mean?

The N35 grade describes the magnetic material rather than the physical holding capacity of the finished magnet.

The numerical grade relates to the maximum energy product of the NdFeB material.

When comparing neodymium magnets with the same dimensions, geometry and magnetisation configuration, different grades can provide different levels of magnetic performance.

However, N35 does not directly specify:

• Pull force
• Surface Gauss
• Holding capacity
• Magnetisation direction
• Pole orientation

These characteristics depend on the complete magnet and application.

Neodymium Iron Boron Rare Earth Material

Neodymium Iron Boron is a high-performance rare earth permanent magnetic material widely used in compact magnetic systems.

NdFeB magnets provide high magnetic performance relative to their size and are commonly used for:

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

This makes neodymium particularly useful in engineered products where available space is limited.

Cylindrical Geometry

The cylinder shape can be useful where a magnet needs to be incorporated into a round hole, tube, housing or mechanical component.

Potential applications include:

• Equipment housings
• Circular recesses
• Sensor systems
• Positioning mechanisms
• Product assemblies
• Fixtures
• Prototype devices

When installing the magnet into a recess, appropriate mechanical clearance should be provided.

Do not force-fit the magnet into an undersized hole, as neodymium is brittle and may crack or chip under excessive mechanical pressure.

Sensors and Instrumentation

Compact neodymium cylinder magnets are commonly incorporated into magnetic sensing systems.

Potential applications include:

• Hall-effect sensors
• Reed switches
• Position sensors
• Proximity detection
• Magnetic switching
• Equipment monitoring
• Instrumentation

Sensor performance depends on:

• Magnetisation direction
• Pole orientation
• Distance between the magnet and sensor
• Sensor sensitivity
• Installation geometry

The magnetisation configuration has not been supplied and should be confirmed where magnetic field direction is critical.

Positioning and Alignment

This compact N35 cylinder magnet can also be incorporated into positioning and alignment systems.

Potential functions include:

• Component locating
• Repeatable positioning
• Magnetic alignment
• Assembly assistance
• Fixture positioning
• Prototype mechanisms

Where multiple magnets are used together, confirm their polarity and orientation before permanent installation.

Magnetisation Direction

Cylinder magnets can be manufactured with different magnetisation directions.

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

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

The actual magnetisation direction and pole orientation have not been supplied and should not be assumed from the cylinder geometry.

Confirm this specification where pole location or field direction is important.

Magnetic Performance

Although the magnetic material is confirmed as N35 grade, actual performance depends on multiple factors.

These include:

• N35 material properties
• Magnetisation direction
• Pole configuration
• Magnetic circuit
• Target steel composition
• Target steel thickness
• Available contact area
• Surface condition
• Air gaps
• Load direction
• Mechanical leverage

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

These values should not be estimated from the N35 grade or 10mm x 10mm dimensions alone.

N35 Does Not Mean 35kg Pull Force

The N35 designation does not indicate a 35kg pull force.

N35 identifies the magnetic material grade.

Pull force is a separate performance measurement affected by:

• Magnet dimensions
• Magnetisation
• Target material
• Target thickness
• Contact area
• Air gaps
• Test configuration

Use a verified pull-force specification where magnetic holding capacity is critical.

Air Gaps and Magnetic Attraction

Even small air gaps can reduce the practical magnetic attraction of compact neodymium magnets.

Potential sources of separation include:

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

For maximum practical attraction, unnecessary separation between the magnet and magnetic target should generally be minimised.

Target Steel Thickness

Where the magnet is used against steel, the properties of the target influence magnetic performance.

Important factors include:

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

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.

Direct Pull vs Shear Force

Magnetic holding performance varies depending on the direction of the applied load.

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

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

Shear performance is influenced by:

• Surface friction
• Contact quality
• Paint and coatings
• Installation orientation
• Air gaps
• Mechanical leverage
• Vibration

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

Bonding a Neodymium Cylinder Magnet

This cylinder magnet can be bonded into an appropriately designed housing or recess.

Before bonding:

• Confirm the required magnetic orientation
• Confirm polarity where multiple magnets are involved
• Clean both bonding surfaces
• Remove grease, dust and contamination
• Select an adhesive compatible with the magnet's actual surface finish
• Provide suitable 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.

Avoid Force-Fitting

Neodymium Iron Boron is hard but brittle.

Do not force this 10mm cylinder magnet into an undersized hole or recess.

Excessive mechanical pressure may cause:

• Chipping
• Cracking
• Splitting
• Fracturing
• Damage to the surface finish

Provide appropriate clearance and use a suitable bonding or retention method.

Do Not Machine Neodymium Magnets

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

Avoid:

• Drilling
• Cutting
• Grinding
• Crushing
• Machining

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

If another size or geometry is required, select a magnet manufactured to the appropriate dimensions.

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 can also be weakly magnetic or non-magnetic and should be tested before relying on magnetic attraction.

N35 Neodymium vs Ferrite Cylinder Magnets

N35 neodymium and ferrite magnets provide different magnetic characteristics.

N35 neodymium magnets generally provide:

• Higher magnetic performance relative to size
• Strong magnetic properties from compact dimensions
• Advantages in space-restricted applications
• Suitability for sensors and engineered assemblies

Ferrite magnets generally provide:

• Lower cost
• Good natural corrosion resistance
• Good resistance to demagnetisation
• Suitability where larger dimensions are acceptable

N35 neodymium is commonly selected where strong magnetic performance from a compact cylindrical magnet is required.

Permanent Magnetic Operation

This N35 neodymium cylinder 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 other magnets and nearby ferromagnetic objects suddenly and should be handled carefully.

Potential hazards include:

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

Neodymium is brittle despite its strong magnetic properties. Avoid uncontrolled collisions and excessive mechanical pressure.

Ingestion Hazard

Small magnets can present a serious ingestion hazard, particularly if more than one magnet is swallowed.

Keep this magnet securely away from babies and children. If incorporated into another product, ensure the magnet is securely retained so it cannot become loose during normal use.

Seek urgent medical attention if magnet ingestion is suspected.

Permanent magnets should also be kept an appropriate distance from pacemakers, implanted medical devices, magnetic storage media, magnetic cards and sensitive electronic equipment.
