Editing Field strength

{{Short description|Magnitude of a vector-valued field}}
In [[physics]], '''field strength''' is the ''[[magnitude (mathematics)|magnitude]]'' of a [[vector (geometry)|vector]]-valued [[field (physics)|field]] (e.g., in volts per meter, V/m, for an [[electric field]] '''''E''''').<ref>{{Cite web |title=What is electric field strength and how is it measured? |url=https://www.techtarget.com/whatis/definition/electric-field-strength |access-date=2022-11-10 |website=WhatIs.com |language=en}}</ref> 
For example, an [[electromagnetic field]] has both [[electric field strength]] and [[magnetic field strength]].
As an application, in [[radio frequency]] [[telecommunications]], the [[signal strength]] excites a receiving antenna and thereby induces a voltage at a specific frequency and polarization in order to provide an input signal to a radio receiver. [[Field strength meter]]s are used for such applications as cellular, broadcasting, wi-fi and a wide variety of other radio-related applications.<ref>{{Cite web |title=Field Strength Monitors & Probes |url=https://www.atecorp.com/category/field-strength-monitors-probes |access-date=November 10, 2022 |website=atecorp}}</ref>
<!--
Magnetic Field intensity is expressed as H; its usual unit is amperes/meter, A/m, A-turn/m, A-t/m.
Magnetic field intensity is equal TO B/u, Where 'B' is magnetic flux density and 'u' is permeability of the medium.--->
