UnitConMagnetic Field Strength
Magnetic field strength, written H, describes the magnetizing force in a magnetic system. It is measured in amperes per meter in SI and oersted in CGS. This converter helps compare modern and older field-strength references. It is useful in electromagnetics, magnetic materials, and engineering design.

Frequently asked questions
Magnetic field strength H describes the magnetizing force, while magnetic flux density B describes the resulting magnetic field in terms of flux per area. They are related but not identical.
The oersted is a CGS unit of magnetic field strength. It still appears in older texts and some materials references.
Earth's field is often discussed more often in flux density terms, but field strength can also be estimated depending on location and local conditions. It is much weaker than engineered magnetic systems.
