fringe field

fringe field

An MRI term for the boundary of the magnetic field surrounding a magnet. Safety requirements dictate that the distances of particular field strengths from the magnet must be known, and that potentially unsafe areas (fringe fields) must be flagged with appropriate warning signs.
Access to areas with field strengths of 5 gauss and higher must be strictly controlled.
