magnetic field
Physics term for the region around a magnet or electric current where magnetic forces are observed. Often used interchangeably with 磁場 (じば), though 磁場 may be more common in everyday contexts.
When an electric current flows, a magnetic field is generated around it.
We developed a device to measure the strength of magnetic fields.
neuro-magnetic field
magnetic field intensity; magnetic field strength
Compound of 磁 (じ, 'magnet') and 界 (かい, 'world' or 'area'), literally 'magnetic area'. The term is a modern coinage for the scientific concept of a magnetic field.
