Virvelströms
Virvelströms, also known as eddy currents, are circular currents of electrical conductivity that are induced in a conductor when it is exposed to a changing magnetic field. This phenomenon was first described by François Arago in 1824 and later explained by Léon Foucault in 1851, leading to the term "eddy currents" sometimes being referred to as Foucault currents.
Eddy currents are generated according to Faraday's law of induction. When a magnetic field through a conductive
The presence of eddy currents can have both beneficial and detrimental effects. In some applications, they
However, eddy currents can also be a source of energy loss and heat generation in electrical devices
