The Gilbert ( unit symbol  Gb , after the English doctor and physicist William Gilbert ) is an outdated unit of the magnetic voltage  U m (= magnetic field strength × path ) in a cgs system for electromagnetic units .

The Gilbert is defined by the work that increases the magnetic potential of a positive unit pole by 1  erg :

with the CGS unit Oe ( Oersted ) for the magnetic field strength.

Conversion in SI units :

with the SI unit A ( ampere ) for the magnetic voltage or the electrical current strength .

Further conversion:

with for the cgs unit Biot .
