Strong Neodymium magnets are an important component to generate movement or to produce renewable energy, a rapidly developing field of expertise which relies heavily on quality products that deliver what they promise. Super strong Neodymium magnets have enormous value in developing industries which rely on permanent and reliable magnetic hold.

 Some forms of electric motors and generators, including cordless electric power tools and wind powered generators, use rare earth Neodymium magnets.  Electric and hybrid vehicles rely heavily on round, rare earth disc magnets that allow them to operate independently or with far less reliance on fossil fuels. Many types of electrical equipment use electromagnetic fields and often require a strong Neodymium permanent magnet to interact with the field and convert it into electric signals, data, audible sound, or in some cases, to activate certain procedures. These types of devices can include microphones, micro speakers, alarms and the actuators of equipment, including vital medical ventilators and respirators.

The value of the super strong Neodymium magnetic bond delivers countless solutions to homeowners, tradespeople and creative teams involved in theatre and television set design and construction or who work in the performing and visual arts sector. They may not look like the Sumo wrestlers of the magnet world, but these small Neodymium disc magnets do some serious heavy lifting.
