In the field of physics, the Weber (often denoted by the symbol ‘Wb’) can be defined as the unit of magnetic flux. As per the International System of Units (often abbreviated to SI), one weber is equal to the magnetic flux in a square meter whose flux density is equal to one Tesla. The SI unit of magnetic flux is named after the German physicist and co-inventor of the first electromagnetic telegraph Wilhelm Eduard Weber. Alternately, the weber can be defined as the magnetic flux that would produce an EMF (or electromotive force) of magnitude 1 volt linking a circuit of one turn if it was reduced to zero at a uniform rate in one second. The SI base units of the weber are kiogram.meter2.second-2.ampere-1 (or kg.m2.s-2.A-1). The weber can also be expressed in terms of the product of coulomb and ohm.
