Abstract
The design of permanent magnet chucks of desired specified attractive force at the base or working face of the chuck is expedited by the discovery of a general correlation between two specific engineering parameters. The attractive force intensity expressed as force per unit chuck working face contact area correlates with the ratio of area of the iron block surfaces at the working face to the area of the permanent magnet surfaces contacting the iron blocks and providing the magnetic flux path to them.
