The highest field strength an accessory produces, measured in Gauss at its surface. Its exact location is set by the coil geometry, and it is the reference against which percentage falloff is measured.
Also known as: Peak Field, Peak Gauss (G), Surface Peak
The field is strongest right at the coil and weakens with distance in every direction. On the on-axis dipole model the report uses, it reaches half its peak strength at about three quarters of a coil radius from center and one tenth at about two radii. A larger coil holds the field up farther out.
