Micro Magnet Neodymium Small Ring/Disc/Block Mini Magnet
Micro magnets, also known as miniature magnets, mini magnets, or
tiny magnets. It is generally agreed that miniature magnets are
limited to the bonded magnets, but YYMAG can manufacture miniature
sintered Neodymium magnets, Samarium Cobalt magnet, Ferrite
magnets, and casting AlNiCo magnets. These specialty magnets have
already served to various kinds of applications, include:
Sensors.
Optical devices.
Micro motors.
Medical devices.
Electroacoustic devices.
If you have an application that calls for micro-sized or miniature
magnets, cintact us for additional assistance. Our friendly,
engineering oriented staff welcomes the opportunity to answer your
questions and assist with all of your magnet needs.
