Neodymium Pot Magnet with Round Hole – 42mm x 7.5mm | Slim Profile

The Neodymium Pot Magnet with Round Hole – 42mm x 7.5mm | Slim Profile is a low-profile rare earth mounting magnet designed for secure mechanical fixing and strong magnetic attachment to compatible ferromagnetic steel surfaces. Measuring 42mm in diameter x 7.5mm high, this compact pot magnet combines high-performance Neodymium Iron Boron (NdFeB) magnetic material with a steel pot housing and a round through-hole for mechanical mounting.

Its slim 7.5mm profile makes this neodymium pot magnet particularly useful where installation height is limited. The round mounting hole allows the magnet to be incorporated into fixtures, brackets, machinery, signage, displays and OEM assemblies using suitable mounting hardware.

The surrounding steel pot helps protect the neodymium magnet while directing and concentrating magnetic flux towards the active working face. This creates a practical magnetic mounting solution for industrial, commercial and general-purpose applications requiring a compact, mechanically secured magnet.

Slim 42mm x 7.5mm Design

At 42mm in diameter and only 7.5mm high, this pot magnet provides a broad magnetic working face while maintaining a low overall profile.

The slim format can be particularly useful for:

• Restricted installation spaces
• Low-clearance equipment
• Thin fixtures and assemblies
• Compact machinery
• Display systems
• Furniture applications
• Custom product designs

Its low height allows the magnet to be incorporated into applications where a taller magnetic assembly may be impractical.

Round Hole for Mechanical Mounting

The integrated round hole allows the pot magnet to be mechanically secured using suitable compatible hardware.

This can provide a practical mounting method for applications where the magnet needs to be fixed to a bracket, panel, fixture or other component.

Unlike a countersunk pot magnet, which is designed to accommodate the tapered head of a compatible countersunk screw, this model features a round mounting hole.

A specific hole diameter and compatible fastener size have not been supplied, so mounting hardware should be selected only after confirming the physical dimensions of the product.

How Does a Neodymium Pot Magnet Work?

A pot magnet combines a permanent neodymium magnet with a steel pot or cup housing.

The steel housing performs two important functions:

• It provides mechanical protection around the brittle magnetic material.
• It helps redirect and concentrate magnetic flux towards the exposed working face.

This construction makes pot magnets particularly effective where magnetic attraction is primarily required from one face of the assembly.

The active face should be positioned directly against compatible ferromagnetic steel for strongest practical performance.

Neodymium Rare Earth Magnetic Performance

This pot magnet uses Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material.

Neodymium magnets are known for providing strong magnetic fields relative to their compact size, making them well suited to space-conscious mounting and holding applications.

As a permanent magnet, this product requires:

• No batteries
• No electrical wiring
• No charging
• No external power supply

The magnetic field remains continuously active.

Magnetic Holding Performance

For strongest practical attraction, the working face of the magnet should make close, flat contact with clean and sufficiently thick ferromagnetic steel.

Actual holding performance depends on factors including:

• Steel thickness
• Steel composition
• Surface flatness
• Available contact area
• Paint and coatings
• Rust or contamination
• Air gaps
• Direction of applied force
• Vibration
• Movement
• Leverage

Even a relatively small gap between the magnet and steel can significantly reduce magnetic attraction.

No specific pull force or Gauss rating has been supplied for this product, so its maximum holding capacity should not be inferred from its 42mm diameter or neodymium construction.

Direct Pull vs Shear Loads

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

Direct pull occurs when force acts perpendicular to the magnetic working face. This generally represents the strongest holding orientation.

Shear loading occurs when the magnet is attached to a vertical surface and the load acts downwards, creating a tendency for the magnet or attached assembly to slide.

Practical holding performance under shear can be considerably lower than under ideal direct-pull conditions.

Vibration, shock and leverage from attached components should also be considered when designing the mounting system.

Mechanical Mounting Applications

The round-hole design allows this pot magnet to be incorporated into a wide range of mechanically secured assemblies.

Potential uses include:

• Mounting brackets
• Equipment fixtures
• Sign systems
• Display hardware
• Cabinet components
• Access panels
• Machinery accessories
• Product assemblies
• Custom fabricated equipment

Mechanical fasteners should be tightened appropriately. Excessive clamping force or overtightening may damage the magnet assembly.

Compatible Magnetic Surfaces

This pot magnet is designed to attract suitable ferromagnetic iron and steel.

Suitable target materials can include:

• Mild steel
• Iron
• Magnetic steel plates
• Suitable machinery frames
• Ferromagnetic brackets and structures

Materials such as aluminium, copper, brass, plastic and timber are not magnetically attracted. Many stainless steel grades also provide little or no magnetic attraction.

Always verify the magnetic properties of the intended target surface before installation.

Installation Considerations

Before installing the pot magnet:

• Confirm the target surface is ferromagnetic
• Clean the magnetic face and mating steel surface
• Maximise flat surface contact
• Confirm the round-hole diameter before selecting hardware
• Use appropriately sized mounting components
• Avoid overtightening the fastener
• Consider the direction of the applied load
• Account for vibration and dynamic movement
• Avoid excessive leverage on the magnet assembly

Where accidental detachment could create a hazard, suitable secondary mechanical retention should be incorporated into the design.

Please Note

This neodymium pot magnet measures 42mm in diameter x 7.5mm high and features a round mounting hole and slim-profile design.

No specific round-hole diameter, compatible fastener size, neodymium grade, coating, pull force, Gauss rating, dimensional tolerance or maximum operating temperature has been supplied. These specifications should not be assumed.

Actual magnetic holding performance depends on the target steel, steel thickness, surface condition, contact area, air gaps, mounting orientation, leverage and dynamic forces.

Neodymium magnets are powerful but inherently hard and brittle. Avoid uncontrolled impacts, excessive mounting pressure and attempts to drill, cut or machine the magnetic material.

This pot magnet should not be used for lifting people, hazardous overhead suspension or safety-critical load retention unless the complete system has been appropriately engineered, tested and rated.

Keep strong neodymium magnets away from children, pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
