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.
The magnetic flux density does not measure how strong a magnetic field is, but only how strong the magnetic flux is in a given point or at a given distance (usually right above the magnet's surface). For the intrinsic order of magnitude of magnetic fields, see: Orders of magnitude (magnetic moment). Note:
By analogy both magnetic field strength $H$ and magnetic flux density $B$ (or their representations by other related variables) are required for quantifying the effects of magnetism in magnetic circuits.
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
24 maj 2022 · F is the force being undergone by the current - measured in Newtons (N). B is the magnetic field strength (or flux density) of the field the charge is in (I.e The number of magnetic field lines per unit area) - measured in Teslas (T). I is current of the current - measured in amperes (A).
Magnetic flux density (\({\bf B}\), T or Wb/m\(^2\)) is a description of the magnetic field that can be defined as the solution to Equation \ref{m0005_eFqvB}. Figure \(\PageIndex{4}\): The magnetic field of a bar magnet, illustrating field lines.
