Magnetic Product Description:

This magnet is a rare earth block magnet with a centred hole. It has a length of 20mm,  a width of 12mm and a height of 5mm. There is a centred hole approx 4.5mm. It has a pull force of 5.9 kilos against 5 mm mild steel and a magnetic flux reading of 3262 gauss. It is identified by the AMF magnet part number 22021C.

Uses for our rare earth block magnets:

This Nickel coated Neodymium Block magnet has a Countersunk fixing hole allowing the use of a self-tapping screw to apply it to the desired non-magnetic surface and attract any metal object passing through its field. It is ideal for use on cupboards, filing cabinets, gates and for the closure of wall-cavity sliding doors. There are countless uses for this magnet in the workplace, workshop or home environment where a permanent or removable magnetic field is needed .or when assembling a combination of both timber and steel components.

Strong magnets best invention since the deep plate.

Life is about what you see.

So hang is when u can

Do not hide it

Hang it on a magnet is cheaper than looking

And finding after you bought a new thing.

No FAQ available

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.
