Room Shielding
 
Magnetic shielding through the use of high permeability material in the walls (plus floor and ceiling) of the magnet room. Room shielding can be complete (e.g., six sides of a box, Faraday cage), or partial if the fringe field is to be reduced only in certain areas (see also Magnetic Shielding).

Self Shielding
 
Magnetic shielding by attaching a high permeability yoke to the magnet (passive shielding) or by incorporating additional magnetic field-generating coils designed to reduce the external field (active shielding). See also Magnetic shielding, Active Shielding and Passive Shielding.

Active Shielding
 
Magnetic shielding through the use of secondary shielding coils designed to produce a magnetic field that cancels the field from primary coils in regions where it is not desired. These coils may be inside the magnet cryostat. Active shielding can be applied to the main magnet or to the gradient magnetic fields.
See also Magnetic Shielding, Self Shielding and Room Shielding.
