Bonded neodymium block magnets combine a hard magnetic powder with a non-magnetic polymer or rubber binder. These highly versatile magnets are able to be machined (unlike standard plated neodymium magnets) and stand up against corrosion. Because they are made of powerful neodymium, these magnets pack incredible strength into extremely small dimensions. Bonded neodymium block magnets are used in a wide variety of consumer and industrial applications, and are sought out when power is needed and space is tight.
