electromagnetic field

Most earlier studies of superradiance assumed that light-matter coupling dominates, modeling the entire atomic group as one large "giant dipole" connected to the cavity's electromagnetic field.

“My own efforts during the past four decades have been dedicated to rescuing the founders from the electromagnetic field we have constructed around them,” he writes.

They identify how fluid moves through rocks by pulsing an electromagnetic field into the earth.

"The metallic tip acts like an antenna and focusses the electromagnetic field in a tiny area below its apex."

The category G4 watch from NOAA’s Space Weather Prediction Center — the second such alert issued this year — warns of the possibility of a solar flare for Thursday and Friday, with a resulting coronal mass ejection from the sun that could disturb Earth’s electromagnetic field.
