About Magnetic Flux Density (B) Units

Magnetic flux density (B), also known as magnetic induction, is a vector field that describes the strength and direction of a magnetic field. It is the amount of magnetic flux per unit area perpendicular to the flux.

  • Tesla (T): The SI unit of magnetic flux density. $1 \text{ T} = 1 \text{ Wb/m}^2$.
    • Millitesla (mT): $1 \text{ mT} = 10^{-3} \text{ T}$
    • Microtesla (µT): $1 \text{ µT} = 10^{-6} \text{ T}$
    • Nanotesla (nT): $1 \text{ nT} = 10^{-9} \text{ T}$ (often used for Earth's magnetic field)
  • Weber/square meter (Wb/m²): Directly equivalent to Tesla.
  • Weber/square centimeter (Wb/cm²): $1 \text{ Wb/cm}^2 = 10^4 \text{ T}$.
  • Weber/square inch (Wb/in²): $1 \text{ Wb/in}^2 \approx 1550.0031 \text{ T}$.
  • Maxwell/square meter (Mx/m²): $1 \text{ Mx/m}^2 = 10^{-8} \text{ T}$.
  • Maxwell/square centimeter (Mx/cm²): Equivalent to Gauss. $1 \text{ Mx/cm}^2 = 10^{-4} \text{ T}$.
  • Maxwell/square inch (Mx/in²): $1 \text{ Mx/in}^2 \approx 1.5500031 \times 10^{-5} \text{ T}$.
  • Gauss (G): The CGS unit of magnetic flux density. $1 \text{ G} = 10^{-4} \text{ T}$.
  • Line/square centimeter (line/cm²): Equivalent to Gauss ($1 \text{ line} = 1 \text{ Mx}$). $1 \text{ line/cm}^2 = 10^{-4} \text{ T}$.
  • Line/square inch (line/in²): $1 \text{ line/in}^2 \approx 1.5500031 \times 10^{-5} \text{ T}$.
  • Gamma (γ): A non-SI unit, often used in geophysics. $1 \text{ γ} = 10^{-9} \text{ T} = 1 \text{ nT}$.
