Magnetic Flux Converter

Magnetic flux (Φ) is the total magnetic field passing through a surface: the field strength times the area it crosses, Φ = B * A when the field is perpendicular. Its SI unit is the weber (Wb), one tesla times one square meter. The CGS unit is the maxwell (Mx), also called a line, one gauss times one square centimeter.

A changing flux is what makes generators and transformers work: one weber of flux falling to zero over one second induces one volt in a loop around it.

How to convert magnetic flux units

Type a value into any field, and every other unit is calculated at once. One weber is 100,000,000 maxwells. For example, 0.002 Wb:

1. In milliwebers: multiply by 1,000.

   0.002 × 1,000 = 2 mWb

2. In maxwells: multiply by 100,000,000.

   0.002 × 100,000,000 = 200,000 Mx

Common conversions

Magnetic flux units

• Weber (Wb): The weber is the base unit and is defined as the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second.
  Conversion Factor: 1 Wb = 1 V·s (volt-second)

• Milliweber (mWb): One Milliweber is equal to one thousandth of a Weber.
  Conversion Factor: 1 mWb = 0.001 Wb

• Microweber (μWb): One Microweber is equal to one millionth of a Weber.
  Conversion Factor: 1 μWb = 0.000001 Wb

• Unit Pole: A magnetic pole is a unit pole if it exerts a force of one dyne on another pole of equal strength at a distance of 1 cm. The strength of any given pole in cgs units is therefore numerically equal to the force in dynes which it exerts on a unit pole 1 cm away.
  Conversion Factor: 1 Unit Pole = 1.256637E-7 Wb = 0.0000001256637 Wb

• Maxwell (Mx): One Maxwell is equal to the magnetic flux across a surface of one square centimeter perpendicular to a magnetic field of one Gauss.
  Conversion Factor: 1 Mx = 1E-8 Wb = 0.00000001 Wb

• Line (l): Line is an equivalent to the Maxwell unit.
  Conversion Factor: 1 l = 1 Mx = 0.00000001 Wb

• Kiloline (kl): One Kiloline is equal to one thousand Line.
  Conversion Factor: 1 kl = 1,000 l = 0.00001 Wb

• Megaline (Ml): One Megaline is equivalent to one million lines.
  Conversion Factor: 1 Ml = 1,000,000 l = 0.01 Wb

• Tesla • m² (T•m²): Represents the magnetic flux density in Tesla, multiplied by the area in square meters.
  Conversion Factor: 1 T•m² = 1 Wb

• Tesla • cm² (T•cm²): Represents the magnetic flux density in Tesla, multiplied by the area in square centimeters.
  Conversion Factor: 1 T•cm² = 0.0001 Wb

• Gauss • cm² (G•cm²): Represents the magnetic flux density in Gauss, multiplied by the area in square centimeters.
  Conversion Factor: 1 G•cm² = 1 Mx = 0.00000001 Wb

• Magnetic Flux Quantum (Φ): The quantum of magnetic flux that can exist in a superconducting ring. It is approximately 2.06783E-15 Wb.
  Conversion Factor: 1 Φ ≈ 2.06783 × 10^(-15) Wb
