Uses for our Rare Earth Block Magnets:
Small Neodymium magnets are used to miniaturise the microphones and speakers in our smartphones and many other high-tech devices that send and receive sound. Tiny magnets inside the microphone of the device act as transducers that convert sound wave vibrations in the air into electrical currents. These electrical signals can then be transmitted, amplified or recorded. Loudspeakers, such as PA systems, use this principle in reverse to convert electric signals into amplified audible sound waves. Most intercom systems and two-way radio transmitters operate using small permanent magnets in the microphone and speaker that are sturdy and reliable for outdoor use. Highly technical micro-devices in medicine and electronics use tiny permanent magnets to actuate processes remotely and without the friction that reduces long term reliability in larger, more mechanised devices. Many warning and safety sensors utilise tiny magnets to detect movement and proximity that can indicate pressures and temperatures that may be approaching dangerous levels. Neodymium magnets have impacted many engineering and scientific methodologies and have helped to initiate the research and development of completely new ones.

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.
