Magnetic Field Strength Units
Magnetic field strength (H), also called magnetizing force, is a measure of the strength of an external magnetic field. Unlike magnetic flux density, it represents the field that would exist in the absence of any magnetic material and is independent of the material's magnetic properties.
- Ampere per meter (A/m): The SI unit of magnetic field strength. It measures the magnetizing force per unit length.
- Oersted (Oe): The CGS unit of magnetic field strength. One oersted equals approximately 79.58 A/m. Named after Hans Christian Ørsted.
Units of Magnetic Field Strength
Magnetic field strength is a fundamental quantity that describes the magnetizing force applied to create a magnetic field. It is essential in the design of electromagnets, transformers, and magnetic circuits, where understanding the relationship between applied current and resulting magnetic field is crucial.

Ampere per meter (A/m)
The ampere per meter is the SI unit of magnetic field strength. It represents the magnetizing force that produces a magnetic field when current flows through a conductor. This unit is fundamental in electromagnetic theory and engineering calculations for magnetic circuits.
-
Oersted (Oe)
The oersted is the CGS unit of magnetic field strength. One oersted equals 1000/(4π) A/m, approximately 79.5775 A/m. Named after Hans Christian Ørsted, the Danish physicist who discovered electromagnetism. This unit is still commonly used in materials science and engineering.

Kiloampere per meter (kA/m)
One kiloampere per meter equals 1000 A/m. This unit is used for measuring strong magnetic fields, particularly in industrial electromagnets and high-power magnetic applications.
-
Ampere per centimeter (A/cm)
One ampere per centimeter equals 100 A/m. This unit provides a convenient scale for measuring magnetic field strength in smaller magnetic circuits and laboratory applications.
-
Milliampere per meter (mA/m)
One milliampere per meter equals 0.001 A/m. This unit is used for measuring weak magnetic fields and in precision magnetic measurements where small magnetizing forces are involved.
-
Milligamma (mγ)
The milligamma is a unit equal to 0.001 oersted, approximately 0.0796 A/m. This unit is sometimes used in geophysics and magnetic surveying for measuring very small magnetic field variations.
