6 FAQs about [Eddy current energy storage]
Do Eddy currents affect magnetic properties?
Currently, the influence of eddy currents on the magnetic properties of some materials has been taken advantage of to develop metacomposites and metamaterials that can improve the design of shielding.
What are eddy currents?
Author to whom correspondence should be addressed. Eddy currents are an electromagnetic phenomenon that represent an inexhaustible source of inspiration for technological innovations in the 21st century. Throughout history, these currents have been a subject of research and technological development in multiple fields.
Can eddy currents be used in applications?
This article motivates the reader to think that not only can the phenomenon of eddy currents be utilized in the applications presented previously, but there are still many applications where the heating, magnetic field variations, and forces caused by eddy currents could be explored.
How do eddy currents manifest?
Beyond ohmic losses, eddy currents manifest themselves through the generation of a reaction magnetic field that interacts with the main magnetic field. According to the Lenz’s law, the magnitude of the reaction magnetic field generated by the eddy currents is opposed to the variation of the main magnetic field that generated them.
Can eddy currents be used to solve Bioelectromagnetic problems?
The magnetic fields induced by eddy currents can also be used in medical applications. The induced magnetic fields can be used to solve bioelectromagnetic problems . Eddy currents find specific applications in the bio-electromagnetic study of the human brain, as documented in references [18, 19, 20].
