magnetic flux
Technical term in physics and electrical engineering; refers to the total magnetic field passing through a given area.
The unit of magnetic flux density is the tesla.
コイルを貫く磁束が変化すると起電力が生じる。
When the magnetic flux passing through the coil changes, an electromotive force is generated.
Compound of 磁 (ji, 'magnetism') and 束 (soku, 'bundle' or 'flux'), a direct translation of the English term 'magnetic flux'.
