The ‘N’ number represents the grade and strength of the magnetic material. N35 is a standard grade (good balance of strength and cost), while N52 and N54 are amongst the strongest commercially available grade.

Rule of Thumb: If size is limited but you need maximum hold, go for N52 or N54. If you have space for a larger magnet, a larger N35 or N42 is often more cost-effective.

While the number (e.g., N35 vs N52) refers to the magnet pull force and strength, the letter suffix indicates the Maximum Operating Temperature. Standard Neodymium magnets (with no letter, e.g., N52) function safely up to 80°C. If you need heat resistant magnets for industrial machinery or motors, you must choose a grade with a high Curie temperature rating to prevent permanent loss of strength:

• Standard 80°C e.g. N52

• Medium Hot 100°C e.g. N35M

• Hot 120°C e.g. N42H

• Super Hot 150°C e.g. N45SH

• Ultra Hot 180°C e.g. N40UH

• Extremely Hot 200°C e.g. N35EH

Standard fridge magnets will not work on glass boards because the glass creates a large gap between the magnet and the metal backplate. You require high-strength Neodymium Skittle Magnets designed specifically to punch through the thickness of the glass.

No. Neodymium magnets are sintered powder; they are incredibly hard and brittle. Trying to drill them will cause them to shatter, and the dust produced is highly flammable.

The solution is to please purchase our pre-manufactured Countersunk Magnets or Adhesive Backed Magnets if you need to fix them to a surface. Alternatively, Magnet Store specialises in the supply of custom manufactured magnets, made exactly to your specifications. 

“Pull Force” is the force required to pull the magnet vertically away from a thick steel plate. Pull forces are measured in optimal conditions, against a very thick iron plate pulled vertically at a very slow speed, in controlled conditions.

If you are using the magnet on a thinner metal (like a filing cabinet) or using it in a “shear” position (sliding down a wall), the holding power will be significantly less (often only 20-30% of the stated pull force). This means you must purchase a stronger magnet to compensate for the sub-optimal conditions. 

This refers to the direction of the magnetic field through the magnet.

Axially Magnetised: The magnetic poles (North and South) are located on the large flat faces of the magnet (e.g., the top and bottom of a disc). This is the standard for most Neodymium disc magnets and countersunk magnets used for holding or mounting.

Diametrically Magnetised: The poles are located on the curved sides (left and right), similar to the poles of the Earth. These are typically used in specialised engineering applications, such as rotational sensors, motors, or creating a magnetic latch with ring magnets.

If you are unsure, most standard applications require Axially magnetised for disc magnets or thickness magnetised for block magnets.

No. Neodymium magnets are not toys. If multiple magnets are swallowed, they can attract each other through intestine walls, causing life-threatening injuries. If you suspect someone has swallowed magnets, ring the emergency services immediately. Keep them out of reach of children and pets at all times.

• Phones/Laptops: generally safe from small to medium magnets, as modern electronics use flash memory (not magnetic hard drives). However, they can interfere with compass/GPS sensors.

• Pacemakers: Keep strong magnets at least 30cm (12 inches) away from heart pacemakers.

• Credit Cards: Yes, direct contact can wipe the magnetic strip.

Permanent magnets are incredibly stable. A Neodymium magnet will lose less than 1% of its strength over 10 years, provided it isn’t damaged or overheated.

Neodymium magnets are brittle ceramics, not solid metal. This means they have no ‘give’ like other metals, so if two strong magnets are allowed to slam together from a distance, the impact force can shatter or chip them. This is not a problem with quality, just a natural property of rare earth magnets. Handle with care and control the closing distance.

Yes. While standard block magnets and discs are pressed, we use sophisticated CNC and cutting machinery with intricate features. We can manufacture steps, grooves, chamfers, and non-standard arcs. Whether you need specialised magnets for miniatures, complex motor segments, or specific industrial magnets, we can produce them to the required specifications. 

For standard commercial runs, our tolerance is typically +/- 0.05mm. However, for precision engineering applications requiring exact fits (such as tiny strong magnets for sensors or aerospace), we can achieve a dimensional tolerance as tight as +/- 0.02mm, subject to geometry. Please specify your tolerance requirements when requesting a quote.

We are flexible. We understand that R&D projects often require small batches initially. We can produce low-volume prototypes (e.g. 1-50 units) to help you validate your design. Once validated, we offer competitive pricing for bulk magnets and full-scale production runs.

For bespoke manufacturing, the standard lead time is approximately 15-20 business days. This includes production, coating, magnetisation, and quality inspection. If you have an urgent deadline for a project, such as a Neodymium magnet based product launch in the UK or an industrial repair, please inform us and we’ll do all we can to assist.

Yes. As a specialist supplier, we can manufacture custom dimensions, grades, or coatings. Please contact our technical team for a quote on custom manufacturing.

Yes. Strong magnets are classified as “Dangerous Goods” for air transport because they can interfere with navigation equipment.

UK Orders: Most UK orders travel by road and are unaffected.

International Orders: We handle all necessary IATA compliance packaging and labeling to ensure your magnets fly safely and legally. Please note this specialised packaging may incur a slightly higher shipping cost for bulk international air freight.

Yes, we accept returns on standard items within 30  days, provided they are in original, unopened condition.

Warning: Please be incredibly careful when repacking magnets for return. If they are not shielded correctly, they can stick to delivery vehicles or get lost in sorting hubs. We recommend reusing the original packaging they arrived in.

Yes, we offer a Click & Collect service from our warehouse in Leigh, Greater Manchester. Please select “Collection” at checkout and wait for your “Ready to Collect” email before travelling to ensure your order is picked and packed.

Yes, we ship globally. However, shipping costs and transit times vary significantly depending on the weight of the magnets and the destination’s customs regulations regarding magnetic goods. Shipping charges are automatically calculated at checkout. Customs duties and taxes are the responsibility of the buyer.
