What is the SI Unit of Magnetic Flux?

SI unit of Magnetic Flux is Weber (Wb)

Weber (Wb) is the SI unit of magnetic flux. It measures the total magnetic field passing through a surface. One Weber is equivalent to one Tesla (T) multiplied by one square meter (m²).

1 Wb = 1 Tm²

The Weber is named after the German physicist Wilhelm Eduard Weber. One Weber is defined as the magnetic flux that, when linking a circuit of one turn, produces an electromotive force of one volt if it is reduced to zero at a uniform rate in one second.

Magnetic flux plays a vital role in electromagnetism, particularly in Faraday’s law of electromagnetic induction, where changes in magnetic flux induce an electromotive force.

Magnetic flux quantifies the strength of magnetic fields and is crucial in engineering applications, such as magnetic materials testing, magnetic resonance imaging (MRI), and designing efficient electrical systems for power generation and transmission.
