The gilbert (symbol: Gb) is an obsolete
unit used in
practical cgs and
CGS-EMU systems to measure
magnetomotive force.
The unit is named for English physicist
William Gilbert.
Definition:
*1 Gb = (1/4π)
Bi-turn
Conversion to the corresponding quantity in the SI, with the unit
ampere-turn
The ampere-turn (A⋅t) is the MKS (metre–kilogram–second) unit of magnetomotive force (MMF), represented by a direct current of one ampere flowing in a single-turn loop in a vacuum. " Turns" refers to the winding number of an electrical ...
