Circuitos magnéticos A12 - Lei de Lenz

Lenz's law is one of the most important laws of electromagnetism and is used to identify the polarity of induced voltage. In the particular case of studies for understanding static and rotating electrical machines, it is used to predict polarities in wound magnetic systems: for example, the polarity in transformers. Lenz's and Faraday's laws are used together to model the induced voltage due to the varying magnetic field in coils. As is standard in the channel's video lessons, there is a solved exercise for better understanding of the theory. This content is taught at the university in the subject Magnetic Circuits and Transformers. ___ Social networks: Facebook:   / eletricaemvideos   Instagram: @eudemario Linkedin:   / eudemario-souza-de-santana-9a483315
