In the International System of Units, the unit of B, magnetic flux density, is the tesla (in SI base units: kilogram per second 2 per ampere), [5]: 21 which is equivalent to newton per meter per ampere. The unit of H, magnetic field strength, is ampere per meter (A/m).

Magnetic flux. This article is about magnetic flux. For the magnetic fields "B" (magnetic flux density) and "H", see Magnetic field. In physics, specifically electromagnetism, the magnetic flux through a surface is the surface integral of the normal component of the magnetic field B over that surface.
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
This dynamic force, generated by the movement of liquid iron in Earth’s outer core, undergoes periodic changes and experiences magnetic north-south flips every few hundred thousand years. Earth’s magnetic field has long been used to aid navigation by aligning compasses to the North pole.
The International System of Units (SI) unit of magnetic field intensity, strictly flux density, most commonly used in geomagnetism is the Tesla. At the Earth's surface the total intensity varies from 22,000 nanotesla (nT) to 67,000 nT.
To further distinguish B from H, B is sometimes called the magnetic flux density or the magnetic induction. The quantity M in these relationships is called the magnetization of the material. Another commonly used form for the relationship between B and H is. B = μ m H. where. μ = μ m = K m μ 0.
