Neodymium Pot Magnet with Round Hole – 32mm x 8mm

The Neodymium Pot Magnet with Round Hole – 32mm x 8mm is a compact rare earth mounting magnet featuring a 32mm diameter, 8mm overall height and central round through-hole for mechanical fastening. Combining powerful Neodymium Iron Boron (NdFeB) magnetic material with a protective steel pot housing, this permanent magnet is designed for holding, positioning, mounting and fixing applications on compatible ferromagnetic steel surfaces.

The surrounding steel pot helps protect the brittle neodymium magnetic material while directing and concentrating magnetic flux towards the active working face. This makes pot magnets particularly effective when positioned against clean, flat and sufficiently thick steel.

Unlike a countersunk pot magnet, this model features a straight round mounting hole rather than a countersunk recess. It is suitable for industrial equipment, fixtures, signage, displays, furniture, cabinetry, machinery and OEM applications where a mechanically secured magnetic mounting point is required.

32mm Diameter x 8mm Low-Profile Design

With a 32mm diameter and 8mm overall height, this neodymium pot magnet provides a compact mounting format for applications where installation depth is limited.

The relatively broad magnetic working face combined with the low-profile body makes this format useful for:

• Shallow mounting locations
• Equipment housings
• Fixtures and brackets
• Displays
• Furniture components
• Panels
• Custom assemblies
• Space-constrained product designs

Always confirm the complete dimensions and available installation space before mounting.

Central Round Mounting Hole

The pot magnet incorporates a round through-hole for mechanical fastening.

This allows a compatible fastener to pass through the magnetic assembly so the magnet can be securely incorporated into a fixture, bracket, product or piece of equipment.

The round hole is not countersunk. A conventional countersunk screw should therefore not be assumed to sit flush within the magnet unless additional mounting components are used.

The specific hole diameter and compatible fastener size have not been supplied and should be confirmed before selecting mounting hardware.

How Does a Neodymium Pot Magnet Work?

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

In this assembly, powerful NdFeB rare earth magnetic material generates the magnetic field, while the surrounding steel pot helps direct and concentrate magnetic flux towards the exposed working face.

When the active face is positioned against suitable ferromagnetic steel, the magnetic circuit is completed through the target material, creating attractive force between the surfaces.

For strongest practical performance, maximise direct contact between the magnetic face and the target steel.

Why Use a Steel Pot Housing?

The steel housing serves two important functions.

First, it provides additional mechanical protection around the neodymium magnetic material. Neodymium magnets are inherently hard and brittle, so protection against impact can be valuable in practical installations.

Second, the steel pot helps redirect magnetic flux towards the active face, creating a concentrated magnetic working surface for attachment to compatible steel.

The strongest attraction is therefore generally associated with the designated working face rather than all surfaces of the assembly equally.

Neodymium Rare Earth Magnet

Neodymium Iron Boron (NdFeB) is a high-performance rare earth permanent magnetic material known for producing strong magnetic fields relative to its size.

This makes neodymium pot magnets useful where compact dimensions and effective magnetic attachment are required.

As a permanent magnet, the assembly requires:

• No electricity
• No batteries
• No charging
• No electrical switching

The magnetic field remains continuously active.

Mechanical Mounting

The central round hole allows the pot magnet to be mechanically incorporated into a larger assembly.

Potential installations include:

• Brackets
• Fixtures
• Machinery
• Equipment
• Display systems
• Signage
• Furniture
• Custom manufactured products

When installing the magnet, use appropriately sized hardware and avoid applying excessive force to the magnetic assembly.

Neodymium is brittle and can crack, chip or fracture if subjected to uncontrolled impact or excessive mechanical stress.

Magnetic Holding and Positioning

Once mechanically installed, the magnet can provide a removable magnetic connection to compatible steel.

This can be useful for applications requiring:

• Removable panels
• Repositionable fixtures
• Magnetic closures
• Equipment covers
• Temporary attachments
• Product positioning
• Detachable displays
• Magnetic locating points

The exact suitability depends on the forces and operating conditions present in the complete application.

Magnetic Holding Performance

Actual magnetic holding performance depends on several factors, including:

• Target steel thickness
• Steel composition
• Surface flatness
• Available contact area
• Paint and coatings
• Rust
• Dirt and contamination
• Air gaps
• Load direction
• Vibration
• Movement
• Leverage

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

No specific pull force has been supplied for this product and holding capacity should not be inferred solely from its 32mm diameter.

Direct Pull vs Shear Force

Magnetic performance differs depending on the direction in which the load acts.

Direct pull occurs when the magnet is pulled perpendicular to the steel surface. This is different from shear loading, where the magnet is subjected to sideways or vertical forces.

In vertical mounting applications, gravity can encourage the magnet to slide across the steel surface before it separates directly.

Practical holding performance can therefore be significantly lower in shear than under ideal direct-pull conditions.

Air Gaps and Surface Coatings

Even a small physical separation between the magnetic face and target steel can reduce magnetic attraction.

Potential air gaps can be created by:

• Paint
• Powder coating
• Protective films
• Adhesive layers
• Dirt
• Rust
• Uneven surfaces

For maximum practical magnetic performance, minimise unnecessary gaps between the pot magnet and the ferromagnetic target.

Compatible Target Materials

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

Suitable target materials can include:

• Mild steel
• Iron
• Magnetic steel plates
• Steel brackets
• Ferromagnetic machinery components

It will not effectively attract aluminium, copper, brass, plastic, timber or glass.

Many stainless steel grades also provide weak or negligible magnetic attraction and should be tested before use.

Installation Considerations

Before installation:

• Confirm the 32mm diameter x 8mm height suits the available space
• Verify the round-hole diameter before selecting hardware
• Use compatible mounting components
• Avoid excessive tightening or mechanical stress
• Identify the magnetic working face
• Ensure the target surface is ferromagnetic
• Maximise flat contact with the target steel
• Minimise coatings and air gaps where possible
• Consider shear, vibration and leverage in the final installation

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

Please Note

This product is a Neodymium Pot Magnet with Round Hole measuring 32mm in diameter x 8mm in overall height.

The central mounting hole is a straight round through-hole and is not specified as countersunk.

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

Actual magnetic holding performance depends on target steel thickness and composition, surface condition, contact area, air gaps, coatings, load direction, vibration and leverage.

Neodymium magnetic material is inherently brittle. Avoid drilling, machining, cutting or modifying the magnet, and prevent uncontrolled impact or excessive mechanical stress.

This pot magnet should not be treated as certified lifting equipment or used as the sole means of supporting safety-critical or hazardous overhead loads.

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