Convert between ampere turn (At), gilbert (Gi), and other magnetomotive force units with scientific precision.
The SI unit of magnetomotive force, defined as the magnetic potential difference across a circuit with one ampere of current flowing through one complete turn of a coil. 1 At = 1 ampere × 1 turn.
Common uses: Electromagnetics, transformer design, relay calculations, magnetic circuit analysis, inductor specifications.
One thousand ampere turns. 1 kAt = 1,000 At. Used for higher magnetomotive force values in large electrical machinery.
Application: Large power transformers, industrial electromagnets, and high-powered electrical equipment.
One thousandth of an ampere turn. 1 mAt = 0.001 At. Used for small signal applications and sensitive magnetic devices.
Application: Small electromagnets, magnetic sensors, low-power relay coils, and precision magnetic instruments.
A CGS (centimeter-gram-second) unit of magnetomotive force. 1 abAt = 10 At. Historical unit still found in older electromagnetic literature.
Historical context: Part of the CGS-EMU system, largely replaced by SI units in modern engineering practice.
A CGS unit of magnetomotive force, approximately 1 Gi ≈ 0.796 At (or 1 At ≈ 1.256637 Gi). Named after physicist William Gilbert.
Relationship: The gilbert is based on the magnetomotive force required to produce a magnetic field of one oersted in a one-centimeter magnetic circuit.
