Abstract :
The parameters of magnetic force, radio-opacity, biocompatability and ease of machining were examined with regard to selecting magnetic materials for use in permanently implanted medical systems. AlNiCo 5, PtCo and SmCo were considered. PtCo was found to be the most suitable. Depending upon the 
ratio of cylindrical magnets, SmCo or AlNiCo 5 develops the greatest force.
ratio of cylindrical magnets, SmCo or AlNiCo 5 develops the greatest force.Keywords :
