In physics, the field strength of a field is the magnitude of its vector value.
In theoretical physics, field strength is another name for the curvature form. For the electromagnetic field, the curvature form is an antisymmetric matrix whose elements are the electric field and magnetic field: the electromagnetic tensor.
In radio frequency telecommunications, field strength is the magnitude of the received electromagnetic field which will excite a receiving antenna and thereby induce a voltage at a specific frequency in order to provide an input signal to a radio receiver for such applications as cellular, broadcasting, wi-fi and a wide variety of other radio-related applications.
Famous quotes containing the words field and/or strength:
“He stung me first and stung me afterward.
He rolled me off the field head over heels
And would not listen to my explanations.”
—Robert Frost (1874–1963)
“Every work of art should give utterance, or indicate, the awful blind strength and the cruelty of the creative impulse, that is why they must all have what are called errors, both of taste and style.”
—Christina Stead (1902–1983)
