Neodymium Block Magnet - 30mm x 12.5mm x 3.3mm

Magnetic Product Description:

This rectangular block magnet has a length of 30mm, a width of 12.5mm and a thickness of 3.3mm. It has a magnetic flux of 2119 Gauss and a pull force against 5mm mild steel of 4.7 kilos. It uses the AMF magnetic part number 22009A


Uses for our rare earth block magnets:

This Neodymium block magnet was originally purchased by a film projector manufacturer for the refurbishment of existing cinema projectors in locations around the world. It is a handy size that has become a popular all-purpose magnet that is also used by visual display companies when creating internal shop fittings and advertising display units.

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.
