Magnetic Product Description:

This neodymium block magnet is 50mm square with a thickness of 25.4mm. It has a pull force of 102 Kilos against 5 mm mild steel. It has a magnetic flux reading of 4200 and is supplied with a Nickel coating. This product uses the AMF magnet part number 22003A.

Uses for our rare earth block magnets:

These strong magnets can be glued and recessed into surfaces to create an invisible closure system or seal with a metallic material or indeed another exact same magnet with its poles in the reverse position. A layer or covering of soft material like cloth can help protect the two magnets from collision damage during a sudden or accidental engagement.Modern and functional designs use magnetic engagement to enhance the appeal of products and increase their level of sophistication.

It is the compatibility of magnets with the dominant material of the modern world ie; plastics, that has proclaimed magnets as the preferred fastener for product designers today. A magnets intuitive release at a predetermined amount of pressure or force, without damaging or compromising any material integrity in the bonding process, provides a superior method of fastening compared to traditional methods and greatly increases the durability, modernity and amenity of a product.

These magnets are popular with engineering firms which manufacture custom magnetic plates and other devices. Also used in roadworks, plumbing for the purpose of retrieving metal swarf and foreign objects and used in the manufacture of scientific equipment. Shopfitting and material handling companies are also regular purchasers of these magnets.

NB: Ranges are indicative for product category, please check individual products for specic values within that range.

The most common coating for Neodymium magnets is Nickel + Copper + Nickel (Ni + Cu + Ni). This coating offers the magnet relatively good protection from corrosion and passive applications. If the magnet will be exposed to moisture or liquid then consider the use of an organic coating such as Epoxy. A hard wearing coating, Epoxy is suited to applications where the magnet will come under some friction or knocking.

Magnets are readily available in Blocks, Discs, Cylinders & Rings. AMF Magnetics specializes in the supply of short-run prototype magnets including Arc Segments, various magnetic orientations etc. If you need a magnet size that we don't carry in stock, submit a Design-a-Magnet enquiry for a quote on your custom magnet design.

Neodymium magnets are offered in several different grades. The first section N30-54 has an operating temperature of up to 80 degrees. Most of our stock only goes up to N38. The second section, denoted with the "M" prefix after the grade has an operating temperature 100 degrees. After this the grades are "H", "SH", "UH" & "EH". In order for the magnet to withstand a higher operating temperature, during production more of the raw material PrNd is incorporated as these elements have a naturally occurring resistance to high temperatures.

Replacement unit of similar size used in construction rigging to anchor/tether equipment/tools.

We have used this type/size sucessfull in the past to tether our tools and equipment while working at heights. We locate the magnet inside our canvas tool bags and find this very convenient form of sucessfull locating our tools/equipment at various work levels where at times no othet suitable anchor is sucessful. We have been very happy with the sucess that these magnets have provided.

Nice magnets.

The surface measurement was just a little under 4000Gauss but nice uniform distribution. I use these magnets for a small NMR measurement system.

I hope to get some discount in case I decide to take them up in production.

They arrived very fast, good service.

Overall happy customer.
