Its low-profile 8mm height can be particularly useful where installation depth is limited.

What Is a Neodymium Pot Magnet?

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

In this product, the magnetic element is manufactured from Neodymium Iron Boron (NdFeB), a high-performance rare earth magnetic material.

The surrounding steel pot helps:

• Protect the magnetic element from direct mechanical contact
• Form part of the magnetic circuit
• Direct magnetic flux towards the active face
• Concentrate the useful magnetic field on the working side of the assembly
• Provide a practical structure for mechanical mounting

This construction makes pot magnets particularly useful where magnetic holding is required primarily from one face.

Central Round Mounting Hole

This pot magnet features a central round hole designed to provide a mechanical mounting point.

Depending on the application, the hole may be used with appropriately selected:

• Bolts
• Screws
• Pins
• Studs
• Other compatible fastening components

The exact hole diameter has not been supplied, so fastener compatibility should be confirmed before installation.

The hole should not automatically be assumed to suit a particular metric or imperial fastener size.

Round Hole vs Countersunk Pot Magnet

A round-hole pot magnet differs from a countersunk pot magnet in the design of its mounting hole.

A round-hole pot magnet uses a straight mounting hole and may suit installations involving a compatible bolt, screw, pin or other mechanical component.

A countersunk pot magnet has a shaped recess designed to accommodate the head of a compatible countersunk screw.

Where a flush screw-head installation is required, a countersunk design may be more appropriate. Where the assembly design calls for a straight through-hole, this round-hole configuration may provide a better solution.

Steel Pot Magnetic Circuit

The steel housing is an important part of a pot magnet's design.

Rather than leaving the neodymium magnetic element completely exposed, the pot helps redirect magnetic flux so that both magnetic poles contribute to the field available at the working face.

This can provide effective magnetic attraction against a compatible flat ferromagnetic surface.

The steel housing also provides some mechanical protection around the magnet, although the assembly should still be protected from excessive impact.

Active Magnetic Face

Pot magnets are primarily designed to provide magnetic attraction from their active working face.

For best practical holding performance, the active face should generally be positioned against:

• Clean
• Flat
• Smooth
• Sufficiently thick
• Ferromagnetic steel

The opposite side and outer steel housing should not be assumed to provide the same magnetic performance as the active face.

Fixtures, Jigs and Positioning

This 32mm round-hole pot magnet can be incorporated into appropriately designed magnetic fixtures and jigs.

Potential functions include:

• Component positioning
• Temporary attachment
• Alignment
• Removable fixture components
• Assembly aids
• Inspection setups
• Custom magnetic mounting

The central hole provides a convenient mechanical integration point while the active magnetic face provides removable attachment to compatible steel.

Equipment and Machinery Mounting

Round-hole neodymium pot magnets can be useful where components need to be attached to existing ferromagnetic machinery or equipment without permanently modifying the steel mounting surface.

Potential applications include:

• Sensors
• Signs
• Guards
• Indicators
• Small equipment accessories
• Inspection devices
• Temporary fixtures
• Removable brackets

The component attached to the pot magnet should be designed so that leverage, vibration and shear loads remain within suitable limits.

Magnetic Signage and Displays

The combination of a compact pot magnet and mechanical mounting hole can also make this product useful for removable signage and display systems.

Potential applications include:

• Warehouse signs
• Equipment identification
• Retail displays
• Exhibition components
• Information panels
• Temporary notices
• Industrial labels and signs

Magnetic mounting allows compatible assemblies to be removed or repositioned without drilling the underlying steel surface.

Magnetic Performance

Practical magnetic performance depends on factors including:

• Neodymium grade
• Pot magnet construction
• Magnetic circuit design
• Target steel composition
• Target steel thickness
• Available contact area
• Surface flatness
• Air gaps
• Paint and coatings
• Load direction
• Mechanical leverage

No specific pull force or magnetic flux density in Gauss has been supplied and these values should not be inferred from the 32mm x 8mm dimensions alone.

Pull Force vs Safe Working Load

A pot magnet's pull force, where specified, is normally measured under controlled test conditions against suitable steel with the magnetic working face in direct contact.

Real-world holding performance can be reduced by:

• Thin steel
• Paint
• Powder coating
• Rust
• Dirt
• Uneven surfaces
• Air gaps
• Side loading
• Vibration
• Mechanical leverage

A pull-force figure should therefore not automatically be interpreted as the amount of weight a magnet can safely suspend in a practical installation.

No pull-force specification has been supplied for this product.

Direct Pull vs Shear Force

Pot magnets generally perform best when the load acts in direct pull, perpendicular to the target surface.

A vertical installation often creates shear loading, where the attached component attempts to slide down the steel surface.

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

• Surface friction
• Target material
• Contact quality
• Surface coatings
• Weight of the attached component
• Mechanical leverage
• Vibration

For vertical mounting applications, test the complete assembly under realistic operating conditions.

Mechanical Leverage

The position of the attached load can significantly affect magnetic holding.

A component positioned close to the magnetic face generally creates less leverage than a long bracket or object extending away from the mounting surface.

Increasing the distance between the load and magnetic face can create a peeling or levering action, making the pot magnet easier to detach.

This should be considered when mounting:

• Long brackets
• Signs
• Equipment
• Sensors
• Fixtures
• Projecting components

Target Steel Thickness

The thickness and composition of the target steel can significantly influence magnetic performance.

A powerful pot magnet attached to very thin steel may not achieve the same holding performance as it would against a suitable thicker steel target.

Important factors include:

• Steel thickness
• Steel composition
• Target dimensions
• Surface flatness
• Magnetic saturation
• Surface coatings

For important holding applications, test the magnet using the actual target material.

Air Gaps and Surface Coatings

Pot magnets generally provide their strongest practical attraction when the working face is in close contact with clean, flat ferromagnetic steel.

Magnetic performance can be reduced by separation created by:

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

Even a relatively small air gap can noticeably reduce magnetic attraction.

Compatible Target Materials

This neodymium pot magnet is designed to attract suitable ferromagnetic materials, including:

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

It will not effectively attach magnetically to inherently non-magnetic materials such as:

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

Many stainless steel grades are also weakly magnetic or non-magnetic and should be tested before relying on magnetic attachment.

Neodymium Pot Magnets vs Standard Neodymium Magnets

A standard neodymium magnet consists primarily of the magnetic material itself, while a neodymium pot magnet incorporates the magnet into a steel housing.

Pot magnet construction can provide advantages including:

• A concentrated working face
• Mechanical protection around the magnetic element
• Convenient mounting features
• Easier integration into fixtures and equipment
• A defined magnetic attachment surface

A standard block or disc magnet may be more appropriate where attraction from multiple sides, a different field configuration or a smaller overall assembly is required.

Permanent Magnetic Operation

This neodymium pot magnet uses a permanent magnetic system.

It requires:

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

The magnetic field remains continuously active during normal operation.

Safety and Handling

Neodymium pot magnets can produce substantial magnetic attraction and should be handled carefully.

Always:

• Keep fingers clear of the magnetic working face during attachment
• Maintain control of the magnet near steel surfaces
• Avoid uncontrolled collisions
• Keep magnets suitably separated during storage
• Use appropriate eye protection where impact or fragmentation is possible

Although the steel pot provides some mechanical protection, the enclosed neodymium magnetic material remains hard and brittle.

Do not drill, cut, grind or machine the magnetic element.

Keep powerful permanent magnets an appropriate distance from:

• Pacemakers
• Implanted medical devices
• Magnetic storage media
• Magnetic cards
• Sensitive electronic equipment

Keep magnets securely away from babies and children.
