Neodymium Block Magnet | Partial Ovoid - 38mm x 29mm x (3mm-5.8mm) | Phosphorus Coating
Magnetic Product Description:
This unusual partial ovoid block magnet has a length of 38mm times a width of 29mm times an ovoid thickness between 3 to 5.8mm. It has the AMF magnet part number 22006C.
Uses for our rare earth block magnets:
The Partial Ovoid Neodymium Block Magnets is probably our most niche magnet available due to its unusual shape and its phosphorous coating. The pull force isn’t displayed as it is difficult to measure on this magnet due to the ovoid shape, although it is still axially magnetised like most other magnets you would encounter. The pull force is not an essential element to this magnet however, it is mostly used within small machinery using its magnetic field to regulate internal components. Most notably is its use within film projectors to modify and manage the movement of the metallic parts in order to produce the smooth and continuous images. In fact, we originally had this magnet manufactured for the Film & Cinema industry. They can be used within various small motors to regulate movement.

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.
