Faraday's law
[FAR-uh-day's law]
noun
Lei de Faraday
1. A fundamental principle in electromagnetism stating that a changing magnetic flux through a closed loop induces an electromotive force (EMF) in the loop
Faraday's law explains how generators convert mechanical energy into electrical energy by rotating a coil in a magnetic field.
A Lei de Faraday explica como geradores convertem energia mecânica em energia elétrica ao girar uma bobina em um campo magnético.
2. The quantitative relationship expressed as the induced EMF equals the negative rate of change of magnetic flux through a circuit
Using Faraday's law, we can calculate the voltage induced in a transformer coil.
Usando a Lei de Faraday, podemos calcular a tensão induzida em uma bobina de transformador.
Faraday's law is a cornerstone of physics education in both Brazil and the USA, taught in secondary schools and universities. Named after English scientist Michael Faraday (1791-1867), it is fundamental to understanding electrical engineering, power generation, and transformer technology. The term is used identically in both Portuguese-speaking and English-speaking scientific communities.
