Reference｜Magnetic field unit

The strength of a magnetic field is represented by a vector quantity that has magnitude and direction (magnetic flux lines).

The number of magnetic flux lines passing through a unit area perpendicular to the magnetic field is called the magnetic flux density B. The relationship between the strength of the magnetic field H and the magnetic flux density B can be expressed by B = μH using the ease of magnetization of an object μ (magnetic permeability).

In the atmosphere, μ is approximately 1, and 1 Gauss ≈ 1 Oersted except for special cases. Magnetic field strength is usually expressed in oersteds, amperes per meter.

Also, when expressing magnetic flux density, units such as gauss and tesla are used.

In other words, the magnetic flux density B can be expressed as a value that includes the ease of magnetization, and the magnetic field H can be expressed as a value that does not include the ease of magnetization.

There are residual magnetic flux density (Br) and coercive force (Hc) to express the characteristics of well-known permanent magnets.

Coercive force is the strength of the magnetic field in the opposite direction that must be applied to reverse the polarity of a magnet, so Oersteds is used.
