Method for assembling magnetic members for magnetic resonance imaging magnetic field generator

A magnetic field generator for a magnetic resonance imaging system comprising:

• an arrangement for a permanent magnet of a magnet assembly comprising a ferromagnetic yoke plate and a permanent magnet, wherein said arrangement includes a portion of a cavity formed from placement of a portion of a plurality of retainers attached at substantially a perimeter of said yoke plate;
• said first portion of said cavity populated with a set of rails attached to said yoke plate;
• a plurality of gliders affixed to a plurality of magnet blocks and magnetized to form a plurality of block assemblies;
• wherein each block assembly of said plurality of block assemblies is slid along a rail of said set of rails;
• initiating with an outermost rail and concluding with an innermost, securing each successively filled rail with a retainer.
