What are Pot Magnets?

Pot magnets are magnetic assemblies consisting of a permanent magnet embedded within a steel housing. The steel shell helps concentrate the magnetic force onto a single gripping surface, thereby enhancing the magnetic strength and making them more suitable for industrial mounting and holding applications than standard, exposed magnets.

Compared to conventional disc or block magnets, pot magnets are easier to install, offer greater stability, and provide better resistance to impact damage. They are particularly well-suited for applications requiring attachment via screws, bolts, hooks, threaded studs, or other mechanical components.
Pot magnets are also known as cup magnets.

Features of Pot Magnets

Pot magnets combine a strong holding force with convenient mechanical installation:

  • Strong Holding Force 
    The steel shell concentrates magnetic power on one working face, achieving high holding strength in a compact size.
  • Easy Installation
    Available with countersunk holes, internal threads, external threads, through holes, hooks, or eyelets, they can be fixed to brackets, panels, tools, or machinery.
  • Removable Fixing
     Ideal for applications requiring temporary attachment without welding or permanent fixtures.
  • Durable and Protected
    The steel housing protects the magnet from physical damage and ensures long-lasting performance.

Common Applications of Pot Magnets

Pot magnets are useful when you need a strong, simple, and removable fixing method on steel surfaces. You can use them for machinery, fixtures, fabrication work, and daily industrial mounting needs.

Machinery and Equipment Mounting

You can use pot magnets to mount panels, covers, sensors, lights, and small accessories on machines without permanent welding or drilling.

Fixtures and Positioning

When you need quick positioning during assembly or production, pot magnets help hold metal parts, brackets, or temporary fixtures in place.

Metal Fabrication and Welding Support

You can use pot magnets to support alignment, temporary holding, and pre-welding positioning for steel plates, frames, and metal components.

Door, Cabinet, and Furniture Fixing

Pot magnets are also suitable for cabinet doors, machine covers, access panels, and furniture parts that require clean and removable magnetic holding.

How to Effectively Use Pot Magnets

-4

Iron blocks can be magnetised to enhanceMoreponerf tnanting e- seetagnetic adsorption.

 
-5

The adsorption position is not at the centre of gravity, easy to drop on one side.

 
-6

The magnetic distance will be greatly reduced by the distance. Please try to reduce the distance.

 
-7

It can adsorb iron, nickel, cobalt, and some of its alloys, but austenitic stainless steel cannot be adsorbed.

 
-8

As the temperature rises, the magnetic force decreases, and at magnetic intensities exceeding 80 °C, demagnetisation occurs.

 
-9

Convex or curved surfaces cannot be completely contacted and will affect the absorption force effect.

How to Choose the Right Pot Magnet

Choosing the right pot magnet depends on how and where you plan to use it. A stronger magnet is not always the best choice if the mounting type, surface, or material is not suitable.

Determine the Holding Direction

You should first check whether the magnet will be pulled straight away from the surface or used against the side sliding force.

Check the Contact Surface

A flat, clean, and thick steel surface gives better holding force. Paint, rust, dust, oil, or gaps can reduce performance.

Select the Installation Type

Choose countersunk, threaded, hook, or rubber-coated pot magnets based on your fixing method.

Choose the Magnet Material

Use neodymium for high strength and ferrite for cost-effective general holding.

Consider Surface Protection

If the surface is painted or easy to scratch, rubber-coated pot magnets are a better choice.

Testing Pot Magnet Pull Strength

For can magnets, pull strength is one of the most critical performance parameters. Before each shipment, we test the pull strength of the batch to ensure it meets the specified requirements. Shipment will only be arranged after the test results are confirmed. This process provides customers with a more transparent and reliable way to verify magnet performance.

Packaging of Pot Magnets

Packaging of Pot Magnets

Our pot magnet packaging is designed to protect the magnets during storage and long-distance shipping. For inner packing, we use plastic or wooden spacers to separate strong magnets and prevent sudden impact, while kraft paper and PE/OPP bags help protect the surface coating from friction, dust, and contamination. Foam boxes can also be used to provide extra cushioning and reduce the risk of collision or edge chipping inside the carton. For outer packing, we use export-grade double-layer corrugated cartons to improve stacking strength and handling safety. Waterproof bag wrapping helps protect the goods from moisture during transit and storage. For heavy or large-volume orders, strong strapping, pallets, or wooden boxes can be arranged to keep cartons stable and make forklift handling easier.

FAQ

Q: What is a pot magnet?

A: A pot magnet is a permanent magnet placed inside a steel cup or steel shell. The steel housing helps concentrate magnetic force on one holding surface and protects the magnet from damage. Pot magnets are also called cup magnets or holding magnets.

Q: What are pot magnets used for?

A: Pot magnets are used for holding, mounting, fixing, positioning, and hanging on steel surfaces. You can use them for machinery, fixtures, signage, tool holding, metal fabrication, cabinets, doors, and removable magnetic mounting.

 

 

Q: How strong are pot magnets?

A: The strength depends on the magnet material, size, structure, and contact surface. Neodymium pot magnets usually provide a stronger holding force than ferrite pot magnets. Clean, flat, and thick steel surfaces give better holding performance.

 

Q: Neodymium vs ferrite pot magnets

A: Choose neodymium pot magnets if you need a strong holding force in a small size. Choose ferrite pot magnets if you need a more economical solution for general holding, signage, outdoor use, or bulk industrial applications.

 

Q: Pot magnets vs disc magnets 

A: For surface holding, pot magnets usually hold stronger than ordinary disc magnets of similar size. The steel shell helps concentrate magnetic force on one side, making pot magnets better for fixing, mounting, and removable holding applications.
