What is Magnetic Field and Flux Density?
Magnetic flux density ($B$) measures magnetic field strength per unit area, carrying SI unit Tesla ($1\,\text{T} = 1\,\text{N}/(\text{A}\cdot\text{m}) = 1\,\text{Wb/m}^2$). The older cgs unit is the Gauss ($1\,\text{T} = 10,000\,\text{G}$). Earth's magnetic field is approximately 0.5 G (50 μT).
Total magnetic flux ($\Phi = \int B \cdot dA$) is measured in Webers in SI and Maxwells in cgs ($1\,\text{Wb} = 10^8\,\text{Mx}$). Magnetic field strength $H$ is measured in $\text{A/m}$ in SI and Oersteds in cgs.
