Gb
- noun
- Archaic
- When testing the coil's strength, they found it required 5 Gb of magnetomotive force.
Examples
-
The motor produced a magnetomotive force of 10 Gb for optimal efficiency.
-
Engineers measured the system's output in Gb to ensure it met magnetism requirements.
-
For example, at the time of this writing, a 1.3GB magneto-optical drive had a street price of about $1,400.

Morphology
Gb = gilbert (transparent) = G + b
The symbol 'Gb' is a conventional abbreviation for the unit name 'gilbert', so the meaning is directly the expanded term for those who know the unit.
Etymology
Gb is a short form of the unit gilbert, named for the English scientist William Gilbert who studied magnets, so think of the common name 'Gilbert' to remember it is about magnetism. A Gb measures the 'push' that creates a magnetic field, which is why engineers use it for magnetomotive force.
