Neodymium Block Magnet - 50mm x 50mm x 50mm
Product code: 22003B

Neodymium Block Magnet - 50mm x 50mm x 50mm
Magnetic Product Description:
This is 50mm square magnet, 50mm in length, width and height. It has a magnetic flux reading of 5754 Gauss and a pull strength of 147 kilos against 5mm mild steel and a coating of nickel. It is an N42 grade neodymium magnet.
Uses for our rare earth block magnets:
Magnets are the ultimate in renewable energy and these extremely powerful permanent magnetic cubes require no external energy source other than to initiate their release at a predictable pressure limit, weight or force.When configured on a gate that is spring- loaded, they instinctively fasten, and release on command at a pre-determined quit force and can do so repeatedly even after long periods of disengagement. This method of fastening and unfastening increases the durability of moving components by graduated, intuitive magnetic control of the open and close procedure.
These magnetic squares are used as an industrial fastener for bonding components and also play a role in cushioning and repelling metal items on a production line that fall within their field.Water conditioning, mining and industrial applications are common for these blocks.
Warning:
This block magnet is extremely powerful, handle with great care as serious injury can occur.

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.
