Abstract
A system and a method for magnetizing one of a plurality of substantially non-magnetized blocks disposed on a plate of a magnetic assembly used in an MRI device are provided. The system includes first and second arm portions operably coupled together. The system further includes a first electromagnetic coil disposed on a first end of the first arm portion, wherein the first electromagnetic coil is configured to generate a magnetic field that propagates from the first electromagnetic coil through at least one non-magnetized block and the plate and further through the first and second arm portions to magnetize the block.

A system for magnetizing one of a plurality of substantially non-magnetized blocks disposed on a plate of a magnet assembly used in an MRI device, comprising:
- first and second arm portions operably coupled together;
- a first electromagnetic coil disposed on a first end of the first arm portion, wherein the first electromagnetic coil is configured to generate a magnetic field that propagates from the first electromagnetic coil through at least one non-magnetized block and the plate and further through the first and second arm portions to magnetize the block;
- and
- a bracket coupled between the first and second arms portions and a movable portion operably coupled to the bracket, wherein an air gap is defined between the first and second arm portions, the moveable portion being configured to be positioned within the air gap to form a magnetic field path between the first and second arm portions.
A method for magnetizing at least one of a plurality of substantially non-magnetized blocks disposed on a plate of a magnet assembly used in an MRI device, comprising:
- disposing first and second arm portions proximate a first non-magnetized block and the plate, respectively, wherein a first electromagnetic coil is coupled to the first arm portion;
- and
- energizing the first electromagnetic coil to generate a first magnetic field that propagates from the first electromagnetic coil through the first non-magnetized block and the plate and further through the first and second arm portions to magnetize the first block.
