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:
“They talk about a woman’s sphere,
As though it had a limit.
There’s not a place in earth or heaven.
There’s not a task to mankind given ...
Without a woman in it.”
—Kate Field (1838–1896)
“It is not alone the fact that women have generally had to spend most of their strength in doing for others that has handicapped them in individual effort; but also that they have almost universally had to care wholly for themselves.”
—Anna Garlin Spencer (1851–1931)
