Magnetic Product Description:

This block magnet is magnetised axially through the 4mm thickness and contains powerful N50 Grade Neodymium material that provides 0.43kg of pull-force. The nickel-plated coating significantly improves durability and this block emits a surface gauss reading of 6740G.

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 with Neodymium magnets in the microphone and speaker that are sturdy and reliable for outdoor use.
Highly technical microdevices in medicine and electronics use tiny permanent magnets to activate processes remotely and without the friction of larger, more mechanised devices that often reduces their long term reliability. Many warning and safety sensors utilise tiny Neodymium magnets to detect movement and proximity of ferrous materials that can indicate pressures and temperatures that may be approaching dangerous levels. Neodymium magnets have impacted many recent engineering and scientific methodologies and have also helped to initiate the research and development of completely new ones.
