Magnetic Force computation for a magnetic separator based on permanent magnet

Suspended permanent magnet separator is widely used in many industrial fields. Magnetic force generated by the magnet should be higher than total value of all other competitor forces to attract the particle towards the magnet. In this paper, Approaching the value of magnetic force generated by the magnet and that required to pull the particle is of a great importance for optimum design of separator. a program simulating numerically nodal magnetic force generated by the magnet was proposed and compared with required magnetic force.
