What are the materials that are used to make the surface of a mechanical chuck?
How are the magnets underneath turned off and on simply by moving the magnets 
back and forth? The mechanical chucks are usually made with a straight line 
pattern of two different materials and the electromagnetic chucks usually have 
circular patterns of two different materials. What are these 
materials,generally,and what are the best?
