System and method for affecting flux of multi-pole magnetic structures

A magnetic flux shielding system, comprising:

• a magnetic structure having a first thickness, said magnetic structure comprising a plurality of magnetic sources, said plurality of magnetic sources including opposite polarity magnetic sources having an opposite polarity orientation, said magnetic structure having a first side and a second side, said second side being opposite said first side, said plurality of magnetic sources extending from said first side of said magnetic structure to said second side of said magnetic structure;
• a first shunt plate associated with said first side of said magnetic structure, said first shunt plate having a second thickness less than said first thickness;
• and
• a second shunt plate associated with said second side of said magnetic structure, said second shunt plate having a third thickness less than said first thickness, said second shunt plate being a removable shunt plate, said first shunt plate and said second shunt plate substantially shielding the flux of the magnetic structure.
