Ley de Faraday La ley de introducción de Faraday establece que la fem inducida en un circuito es directamente proporcional a la razón de variación del flujo magnético a través del circuito. Esto es: ε= Donde φm es el flujo magnético dado por: Φm=

Cuando una barra conductora de longitud l se mueve a través de un campo magnético B es perpendicular a la barra, la fem inducida en la barra (llamada fem de movimiento ) esta dada por: ε=-B l o
La ley de Lenz establece que la corriente inducida y la fem inducida en un conductor están en una dirección tal que se oponen al cambio que las produce.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
