1. Plural of permeance; the quality or state of being permanent or lasting.
Usage: Formal or technical usage; Often used in physics and engineering contexts
2. In physics and magnetism, the reciprocal of reluctance; a measure of the ability of a material to support magnetic flux.
Usage: technical; physics/engineering term

Examples

• The permeances of different materials vary significantly in magnetic applications.
• Engineers must consider the permeances of various alloys when designing transformers.
• The permeances of these structures ensure their long-term reliability.
• In circuit design, permeances help determine how efficiently magnetic flux is transmitted.
• The study compared the permeances of iron and steel samples under different conditions.
