Gilbert

Gilbert is the CGS system unit of magneto-motive force. The equivalent SI unit is Ampere-turn, and 1 Gilbert = 10/4π or 0.7958 Ampere-turns. When measuring the operate AT of a reed switch using a simply power supply and a coil, it is easy to calculate the operate AT by just noting the operate current and multiplying it with the number of turns in the test coil.

Gilbert_(unit) (Wikipedia)

The gilbert (Symbol: Gb) is an obsolete unit used in practical cgs and emu cgs systems to measure magnetization. The unit is named for English physicist William Gilbert.

Definition in magnetization:

  • 1 Gb = (1/4π)×Bi-turn

Conversion to Ampere-turns:

  • 1 Gb = (10/4π) A-turn= 0.7957747 A-turn
  • 1 A-turn ≡ 4π * 10−1 Gb
