Magnetic Flux Converter

About Magnetic Flux (Φ) Units

Magnetic flux is a measure of the total magnetic field that passes through a given area. It is often denoted by the symbol Φ (Phi).

• Weber (Wb): The SI unit of magnetic flux. $1 \text{ Wb} = 1 \text{ T} \cdot \text{m}^2$.
  • Milliweber (mWb): $1 \text{ mWb} = 10^{-3} \text{ Wb}$
  • Microweber (µWb): $1 \text{ µWb} = 10^{-6} \text{ Wb}$
• Maxwell (Mx): The CGS unit of magnetic flux. $1 \text{ Wb} = 10^8 \text{ Mx}$. Thus, $1 \text{ Mx} = 10^{-8} \text{ Wb}$.
• Tesla square meter (T·m²): This is equivalent to the Weber. $1 \text{ T} \cdot \text{m}^2 = 1 \text{ Wb}$.
• Tesla square centimeter (T·cm²): $1 \text{ T} \cdot \text{cm}^2 = 1 \text{ T} \cdot (10^{-2} \text{ m})^2 = 10^{-4} \text{ T} \cdot \text{m}^2 = 10^{-4} \text{ Wb}$.
• Gauss square centimeter (G·cm²): This is equivalent to the Maxwell. $1 \text{ G} \cdot \text{cm}^2 = 1 \text{ Mx}$. (Since $1 \text{ T} = 10^4 \text{ G}$, then $1 \text{ G} = 10^{-4} \text{ T}$. So $1 \text{ G} \cdot \text{cm}^2 = 10^{-4} \text{ T} \cdot 10^{-4} \text{ m}^2 = 10^{-8} \text{ Wb} = 1 \text{ Mx}$).
• Magnetic flux quantum ($\Phi_0$): A fundamental constant of nature. $\Phi_0 = h/(2e) \approx 2.067833848 \times 10^{-15} \text{ Wb}$.
• Unit Volt Second (V·s): Equivalent to Weber. $1 \text{ V} \cdot \text{s} = 1 \text{ Wb}$.
• Weber/ampere (Wb/A): This is the unit of Inductance (Henry), not directly magnetic flux. However, it's listed on the page, possibly in a different context or as related. For a flux converter, it's unusual. I will include it if it's meant to be directly converted as a flux unit, assuming a 1:1 relation to Weber if no other factor is implied. The site lists it as $1 \text{ Wb/A} = 1 \text{ Wb}$ for the purpose of their converter.
