Definition
Noun: - A magnetomotive force unit is a standard quantity used to measure magnetomotive force. Magnetomotive force is the force that sets up a magnetic field within a magnetic circuit, analogous to electromotive force (voltage) in an electrical circuit.
Usage
- This term is used in the context of physics and electrical engineering to specify the unit for quantifying the magnetomotive force in a system.
- It is a technical, compound noun phrase. The core concept is the for measuring .
Examples
- The ampere-turn is a common magnetomotive force unit.
- When designing an electromagnet, you must calculate the required magnetomotive force and express it in the appropriate magnetomotive force unit.
Advanced Usage
- In the International System of Units (SI), the ampere (or ampere-turn) is the base magnetomotive force unit.
- The unit gilbert is a CGS (centimetre-gram-second) system magnetomotive force unit.
Variants and Related Words
- Ampere-turn (A·t or At): The SI-derived unit of magnetomotive force, equal to the magnetomotive force produced by a current of one ampere flowing through one turn of a coil.
- Gilbert (Gb): A CGS unit of magnetomotive force, approximately equal to 0.7958 ampere-turns.
Synonyms
- MMF unit: An abbreviation for magnetomotive force unit.
Notes
- The term itself is a specific, technical label for a class of measurement units. It is not typically used in idioms or phrasal verbs.
Noun
- a unit of measurement of magnetomotive force
