About This Tool

This Magnetic Field Strength Converter is a tool for physics and engineering that deals with the properties of magnetic fields. It converts units of magnetic field strength (H-field), which is a measure of the intensity of a magnetic field. The base unit is the ampere per meter (A/m).

The H-field is distinct from the magnetic flux density (B-field, measured in teslas). The H-field represents the 'effort' put into creating a magnetic field in a given medium, while the B-field represents the resulting 'effect' or flux density. This tool is key for designing magnetic circuits and understanding magnetic materials.

Tips & Features

  • Ampere per Meter (A/m): The ampere per meter is the SI unit for magnetic field strength. It is equivalent to the linear current density on a surface that would produce such a field.
  • Oersted (Oe): The oersted is the corresponding unit in the CGS system. It is commonly used in the magnetics industry in the US to specify properties of permanent magnets and magnetic materials.
  • H-field vs. B-field: In a vacuum, the B-field and H-field are directly proportional (B = μ₀H, where μ₀ is the permeability of free space). In a magnetic material, the relationship is B = μH, where μ is the permeability of the material.
