Unit Explanations
Milliampere TurnmAt
Source UnitThe milliampere turn (mAt) is a unit of magnetomotive force that quantifies the magnetizing effect produced by an electric current flowing through a coil of wire. It is defined as the product of the current in milliamperes and the number of turns in the coil. Specifically, 1 milliampere turn is equivalent to 1/1000 of an ampere multiplied by the number of turns, reflecting a smaller scale of measurement, useful in applications with low currents. This unit is crucial in the design and analysis of magnetic circuits.
Current Use
The milliampere turn is widely used in electrical engineering and physics to quantify the magnetomotive force in low-power magnetic circuits. It is particularly relevant in the design of transformers, inductors, and magnetic sensors where small currents are involved. This unit helps engineers calculate the necessary current and turns in a coil to achieve desired magnetic properties for various devices.
Fun Fact
The milliampere turn is often used in the design of small electronic devices where space and precision are crucial.
GilbertGi
Target UnitThe gilbert (symbol: Gi) is the unit of magnetomotive force (MMF) in the centimeter-gram-second (CGS) system of units. It is defined as the amount of magnetomotive force required to produce a magnetic field of one oersted in a magnetic circuit of one centimeter length with a magnetic permeability of one. This unit is essential in the study of magnetism and is used to express the strength of magnetic sources. One gilbert is equivalent to 10^9/(4π) ampere-turns, reflecting its relationship to the fundamental SI unit of current.
Current Use
The gilbert is primarily used in specialized fields such as electromagnetism and magnetic engineering. While the SI unit of magnetomotive force is the ampere-turn, the gilbert still finds relevance in educational contexts and certain technical applications where the CGS system is applied. It allows for ease of understanding in magnetic circuit analysis.
Fun Fact
The gilbert was one of the first units to quantify magnetomotive force, setting a precedent for future measurements in electromagnetism.

Definition
The milliampere turn (mAt) is a unit of magnetomotive force that quantifies the magnetizing effect produced by an electric current flowing through a coil of wire. It is defined as the product of the current in milliamperes and the number of turns in the coil. Specifically, 1 milliampere turn is equivalent to 1/1000 of an ampere multiplied by the number of turns, reflecting a smaller scale of measurement, useful in applications with low currents. This unit is crucial in the design and analysis of magnetic circuits.
History & Origin
The concept of magnetomotive force arose in the early 19th century with the development of electromagnetic theory, particularly through the works of André-Marie Ampère and Michael Faraday. Their foundational principles led to the formalization of units that describe the effects of electric current on magnetic fields. The milliampere turn specifically emerged as electrical engineering evolved, allowing for more precise calculations in magnetic circuits, especially in small-scale applications.
Etymology: The term 'milliampere' comes from the Latin prefix 'milli-' meaning 'one thousandth' and 'ampere,' named after André-Marie Ampère, a pioneer in electromagnetism. 'Turn' refers to a complete loop of wire in a coil, indicating the number of loops contributing to the magnetic field.
Current Use
The milliampere turn is widely used in electrical engineering and physics to quantify the magnetomotive force in low-power magnetic circuits. It is particularly relevant in the design of transformers, inductors, and magnetic sensors where small currents are involved.
