What is magnetic field strength? – TechTarget Definition
Magnetic field strength is a measure of the intensity of a magnetic field in a given area of that field. Represented as H, magnetic field strength is typically measured in amperes per meter ( A/m ), as defined by the International System of Units ( SI ). Ampere and meter (or metre) are SI base units constructed from the SI's defining constants.
