Neodymium Block Magnet | Partial Ovoid - 62mm x 29.1mm x (3mm-5.8mm) | Phosphorus Coating

Magnetic Product Description:

This unusual partial ovoid block magnet has a length of 62mm times a width of 29.1mm times an ovoid thickness between 3 to 5.8mm. It has the AMF magnet part number 22001.


Uses for our rare earth block magnets:

Magnets like these neodymium blocks would have been installed in film projectors to regulate the movement of metallic parts. The speed at which individual frames containing the filmic images pass over the projector’s light beam is vital. Moving images moving too fast or too slow disorients the viewer, countering the suspension of belief or emotional investment the filmmakers are asking audiences to make.

Rare earth block magnets express instinctive or intuitive magnetic power. Nearby metallic components can move, but only at pull or quit the magnetic grip force determined by the magnet’s strength. That is the intuitive or instinctive nature of magnetic power.

We originally had this magnet manufactured for the Film & Cinema industry. It is used in part of the componentry that makes up a film projector used in the older style cinemas of the past. These particular movie projectors are still used to this day and we believe there are several hundred in operation worldwide. We presently have about seven hundred pieces in stock and will not be replacing this size once all stock has been sold.

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.
