![]() Before we start appreciating his great works, let us understand the concept of magnetic flux, which plays a major role in EMI.įor calculating the magnetic flux, we consider the field-line image of a magnet/the system of magnets, as shown in the image below: Faraday made several contributions to science (especially in magnetism) and till present, he is widely known as the greatest experimental scientist of the nineteenth century. Here, we can rewrite the above equation asĬosθ = The angle between the planar area and the magnetic flux.įaraday’s awesome insights lay the foundation for finding a simple mathematical relation to elaborate the explanation of the series of experiments that he conducted on electromagnetic induction (EMI). So, the magnetic flux depends on both the magnetic strength and the area. Also, A = perpendicular area through which magnetic field lines cross. It is measured in SI base units of Ampere per metre or A/m. It is also the unit of flux density.ī = Magnetic field strength. ![]() Here, Tesla is equal to Weber per metre square. Where ɸ = magnetic flux, where the unit of magnetic flux is Weber (Wb) or Tesla metre squared or (Tm 2 ). In mathematical terms, we can reinstate the above statement as Do you know what flux is and what is the SI unit of magnetic flux? Well, flux is the number of magnetic field lines passing through a cross-sectional area perpendicularly.Ī magnetic flux is the product of the average magnetic field and the perpendicular area that it penetrates. In this article, we will understand the flux definition with various flux units in detail. A change in flux of one weber per second induces an electromotive force of one volt, or it produces an electric potential difference of one volt across two open-circuited terminals. In terms of Faraday’s law, the SI unit of flux is Weber, it is related to a changing magnetic flux through a loop to the electric field around the loop. Weber is the unit of magnetic flux that causes the electromotive force of one volt in a circuit of one rotation when generated/removed in one second. It does not store any personal data.In the 19th century, the Weber unit of magnetic flux was named as an honour to a German Physicist named Wilhelm Eduard Weber (1804-1891).
