permeance
Definition
- Noun (Physics, Electrical Engineering):
- Magnetic permeance: "Permeance" is the measure of the ease with which a magnetic flux can pass through a material or a magnetic circuit. It is the reciprocal of magnetic reluctance and is analogous to electrical conductance.
- General sense: The property of allowing something (such as a fluid or magnetic field) to pass through or permeate a substance.
Usage Examples
- (The material's ability to conduct magnetic flux easily.)
- (The magnetic conductivity of the component.)
- (The ease with which a substance passes through a barrier.)
Advanced Usage
- "Magnetic permeance": In electrical engineering, permeance (symbol: Λ or P) is used in the design of magnetic circuits, such as in motors, transformers, and inductors.
- The total permeance of the magnetic circuit determines the flux density for a given magnetomotive force. (The overall ease of flux flow in a closed loop.)
- "Permeance coefficient": A ratio used in permanent magnet applications to describe the operating point of a magnet.
- The permeance coefficient of the magnet was optimized for maximum efficiency in the generator. (A design parameter for magnetic performance.)
Variants and Related Words
- Permeant (adj): having the ability to permeate or pass through.
- The permeant gas diffused quickly through the porous material. (The substance that can pass through.)
- Permeability (n): the property of a material that allows fluids or magnetic fields to pass through it (a broader term often used in physics and geology).
- The soil's permeability affects groundwater flow. (The ability of water to pass through soil.)
- Permeate (v): to spread or flow throughout something.
- The smell of coffee permeated the room. (It spread through the entire space.)
Synonyms
- Conductance (in magnetic contexts): the measure of ease of flow for magnetic flux.
- Permissivity (rare): a less common synonym for the ability to allow passage.
