Small
Magnet
Johnsonmag has acquired a great experience
and new technologies in machining permanent magnets
or other material in small sizes and different shapes,
especially some micro holes. These small magnets are
required with high precision in special sizes and tolerances
fields like:Micro-motors; micro-mechanical devices;
medical; defense; photonic and other applications.
