Problems Of Intense Magnetic Field In Gravitati... Instant

: These are global electromagnetic resonances excited by lightning strikes in the cavity between the Earth's surface and the ionosphere. They create magnetic fields that are coherent over thousands of kilometers, potentially causing correlated noise between distant detector sites.

: Fluctuating magnetic fields induce currents in the conductive structures of the detector (like the "payload" holding the mirrors), which in turn create secondary magnetic fields and forces. Problems of intense magnetic field in gravitati...

: Devices within the observatory itself—such as power grid cables, motors, pumps, and electronics—generate localized magnetic fields that can interfere with sensitive detector components. : These are global electromagnetic resonances excited by

Magnetic interference in GW detectors stems from both natural and human-made sources: Problems of intense magnetic field in gravitati...

Magnetic fields interfere with the interferometer through several "coupling" mechanisms:
