Magnetic Product Description:
These rare earth disc magnets have a diameter of 30mm and a height of 10mm. They have a magnetic flux reading of 3495 Gauss and a pull force of 19.3 kilos. It is identified by the AMF magnet part number 20002.
Uses for our rare earth disc magnets:
Entities supplying engineering equipment to offshore oil and gas platforms make sure they pack plenty of these neodymium disc magnets for the long trip out to sea. They deliver miles of steel wire ropes, chains, slings and associated fittings for lifting, carrying and holding along with everything else a huge industrial platform may need in the way of engineering equipment. Wherever steel products go, magnets are right alongside them, including these versatile all-rounders. Valued for their fastening, hold and release connective properties, magnets help keep these drilling and pumping platforms safe and operational in one of the harshest environments on earth.
Apparatus involved in lifting holding and releasing of mining and pumping equipment can be found in other industries, but apparatus for holding and releasing the off-shore rig itself, sometimes anchored to the ocean floor, is a scope of another magnitude. Commonplace are steel wire ropes as thick as a man’s torso, single drop forged hooks the size of a double bed and as thick as the mattress.
As well as applications throughout the offshore platform's operations, magnets are used in conjunction with fail-safe devices embedded in some of this extreme scale and equipment. In an emergency, these safety devices, with the aid of magnets, release their hold when required, at a pre-determined load or weight.
That is, the apparatus will fail under certain stresses, but at a point of the engineer’s choosing. The engineers cannot afford undetermined forces to determine where the break in the apparatus will occur in the event of an emergency. This inherent characteristic of magnets allows sacrificing one part of the apparatus, to preserve another.
Magnets with their trusted and accurate pull force properties allow the engineer to determine how much force needs to be applied to the apparatus to trigger the fail-safe device. This principle o inbuilt redundancy under certain conditions, like cyclonic weather for instance, applies across the fixing holding and carrying procedures on offshore oil and gas rigs. Miners operating deep in the ocean hundreds of miles from solid ground require the highest levels of vigilance when managing their operations. With the help of these neodymium disc magnets and others like them, offshore mining can remain a viable and safe form of resource production.

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.
