Magnetic Flux Converter — Weber (Wb), Maxwell (Mx)
Convert between 5 units of magnetic flux — weber (Wb), milliweber (mWb), microweber (μWb), maxwell (Mx), and kiloweber (kWb). Faraday's law states that changing magnetic flux induces an EMF — the principle behind every generator, transformer and induction motor. 1 Wb = 10⁸ Mx. A typical transformer core carries a few milliwebers. The flux quantum in superconductors is 2.068 × 10⁻¹⁵ Wb.
About the Magnetic Flux Converter
Magnetic flux measures the total magnetic field passing through a given surface area — the product of the field strength and the area component perpendicular to the field. The SI unit is the weber (Wb), where 1 Wb = 1 V·s. Faraday's law of induction states that a changing magnetic flux induces an EMF equal to the rate of flux change — the principle behind every generator, transformer, and induction motor in the world.
