The Neodymium Cylinder Magnet – 2mm x 2mm | N50 | Pack of 100pcs is a bulk pack of 100 miniature rare earth permanent magnets, each measuring just 2mm in diameter x 2mm long. Manufactured from high-performance N50 grade Neodymium Iron Boron (NdFeB), these tiny cylindrical magnets provide high magnetic energy density in an extremely compact format.

With an equal 2mm diameter and 2mm length, each magnet has a compact cylindrical profile suitable for applications where installation space is extremely limited. The 100-piece pack is particularly useful for miniature product assemblies, electronics, sensors, precision mechanisms, models, prototypes, manufacturing, research and OEM production where multiple magnets of the same size and grade are required.

N50 is a high-performance neodymium grade, making these magnets particularly useful where magnetic performance relative to physical size is important. Due to their extremely small dimensions, careful handling and secure installation are essential, especially when magnets are incorporated into products that could become accessible to children.

Also known as 2mm neodymium cylinder magnets, N50 micro magnets, miniature rare earth magnets, tiny NdFeB cylinder magnets, 2mm rare earth magnets or miniature cylindrical magnets, these magnets provide permanent magnetic operation without electricity, batteries or charging.

Their compact geometry can be useful where:

• Installation space is extremely limited
• A discreet magnetic component is required
• Magnets need to fit inside miniature housings
• Multiple magnets are incorporated into a small assembly
• Product miniaturisation is important
• A small permanent magnetic source is required

The stated 2mm x 2mm dimensions describe the physical geometry of each magnet and do not represent pull force or holding capacity.

N50 Grade Neodymium

These miniature magnets are manufactured from N50 grade Neodymium Iron Boron, a high-performance rare earth permanent magnetic material.

N50 provides high magnetic energy density, making it useful for applications where significant magnetic performance is required from very small magnet dimensions.

Potential advantages include:

• High magnetic performance relative to volume
• Extremely compact dimensions
• Suitability for miniature components
• Permanent magnetic operation
• Integration into space-constrained products

What Does N50 Mean?

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

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

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

N50 also does not directly specify:

• Pull force
• Surface Gauss
• Holding capacity
• Safe working load
• Magnetisation direction
• Pole configuration
• Maximum operating temperature

These properties depend on the finished magnet and complete magnetic circuit.

High Magnetic Performance in an Extremely Small Format

One of the main advantages of neodymium magnetic material is its ability to provide high magnetic energy from compact dimensions.

At only 2mm x 2mm, these N50 cylinders can be incorporated into products where larger magnetic components would be impractical.

Potential functions include:

• Magnetic attraction
• Positioning
• Alignment
• Sensing
• Switching
• Component retention
• Miniature closures
• Product integration

Actual magnetic performance depends on the complete application rather than magnet grade alone.

Electronics and Sensor Applications

Miniature cylinder magnets can be useful in compact sensing and electronic systems.

Potential applications include:

• Hall-effect sensors
• Reed switches
• Position sensors
• Proximity detection
• Magnetic switching
• Movement detection
• Miniature instrumentation

Sensor response depends on:

• Magnetisation direction
• Pole orientation
• Magnet-to-sensor distance
• Sensor sensitivity
• Installation geometry
• Surrounding magnetic materials

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

Miniature Product Assemblies

The extremely small 2mm x 2mm dimensions make these magnets suitable for integration into miniature components and products.

Potential uses include:

• Small mechanisms
• Miniature closures
• Models
• Precision assemblies
• Electronic devices
• Removable components
• Prototype products
• Custom manufactured items

Because these magnets are extremely small, they should be securely retained within the finished assembly.

This is particularly important where a product could be accessible to children.

Magnetisation Direction

Cylinder magnets can be manufactured with different magnetic orientations.

A 2mm diameter x 2mm long cylinder magnet could potentially be:

• Axially magnetised through its 2mm length
• Diametrically magnetised across its 2mm diameter
• Manufactured with another specialised magnetic configuration

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

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

Magnetic Performance

Although these magnets are confirmed as N50 grade, practical magnetic performance depends on factors including:

• N50 material properties
• Magnet dimensions
• Magnetisation direction
• Pole configuration
• Magnetic circuit
• Target material
• Target steel thickness
• Contact area
• Surface condition
• Air gaps
• Load direction
• Installation geometry

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

These values should not be inferred from the N50 grade alone.

Air Gaps Are Critical with Micro Magnets

Physical separation can significantly reduce magnetic attraction.

This is especially important for a magnet measuring only 2mm x 2mm, because even a very small gap can represent a substantial proportion of the magnet's overall dimensions.

Potential sources of separation include:

• Adhesive
• Paint
• Plastic housings
• Protective films
• Product casings
• Fabric
• Paper
• Mechanical clearance

Where maximum magnetic interaction is required, unnecessary air gaps should be minimised.

Bonding 2mm Neodymium Magnets

Adhesive bonding is one possible method of installing miniature magnets into a product.

Before bonding:

• Confirm the required polarity
• Confirm magnetic orientation
• Clean the bonding surfaces
• Remove grease, dust and contamination
• Select an adhesive suitable for the actual magnet finish
• Provide appropriate dimensional clearance
• Avoid force-fitting
• Allow the adhesive to cure fully

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

Polarity in 100-Piece Production Packs

When installing these magnets in quantity, check polarity before permanent assembly.

Incorrect orientation can cause magnets that are intended to attract to repel instead.

A consistent polarity-checking process can be particularly useful for:

• Batch manufacturing
• Sensor assemblies
• Magnetic closures
• Paired components
• Repetitive assembly
• OEM production

Avoid Force-Fitting

Neodymium Iron Boron is hard but brittle.

Do not force these tiny magnets into undersized recesses or housings.

Force-fitting may cause:

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

Provide appropriate clearance and use a suitable retention method.

Do Not Machine Neodymium Magnets

These miniature magnets should not be mechanically modified.

Avoid:

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

Their extremely small dimensions and brittle NdFeB construction make conventional machining impractical and likely to damage the magnets.

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 may also be weakly magnetic or non-magnetic.

Test the actual target where magnetic compatibility is important.

N50 Neodymium vs Ferrite Magnets

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

N50 neodymium is particularly useful for:

• Miniature components
• Space-constrained assemblies
• Electronics
• Sensors
• 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 performance relative to size is acceptable

For extremely small magnets such as these 2mm x 2mm cylinders, neodymium provides significant advantages where miniaturisation is important.

Permanent Magnetic Operation

These N50 cylinder magnets are permanent magnets.

They require:

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

Their magnetic fields remain continuously active during normal use.

Safety and Handling

These 2mm x 2mm neodymium magnets present a serious ingestion hazard due to their extremely small size.

Keep all magnets securely away from babies and children.

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

If these magnets are incorporated into another product, they should be securely retained so they cannot become detached during normal or foreseeable use.

Permanent magnets should also be kept an appropriate distance from:

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

Neodymium magnets are brittle and can chip or fracture if allowed to collide with each other or ferromagnetic objects.

Please Note

This product contains 100 individual N50 Neodymium Cylinder Magnets, each measuring 2mm in diameter x 2mm long.

The N50 designation identifies the Neodymium Iron Boron magnetic material grade and does not mean each 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, contact area, surface condition, air gaps, load direction and installation geometry.

Because each magnet measures only 2mm x 2mm, these magnets are a serious swallowing hazard and must be kept securely away from babies and children. Where incorporated into another product, suitable measures should be taken to prevent the magnets from becoming detached.

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

The stated 2mm diameter x 2mm length describes the physical dimensions of each magnet and does not represent pull force, holding capacity or safe working load.

These magnets are not certified lifting equipment and should not be used for overhead or safety-critical lifting.
