#### Magnetic field Wikipedia

In the International System of Units, H, magnetic field strength, is measured in the SI base units of ampere per meter (A/m). B, magnetic flux density, is measured in tesla (in SI base units: kilogram per second 2 per ampere), which is equivalent to newton per meter per ampere. H and B differ in how they account for magnetization.The difference between measuring magnetic flux and,Jul 30, 2020· A represents the area of the surface. Where the surface is perpendicular to the magnetic field, cosθ = 1. Where the surface is at an angle to the lines of force, cosθ is less than one. The SI unit of magnetic flux is the Weber. Flux density is magnetic flux divided (vectorially if it is at an angle) by the area of the surface in tesla units.
