20.1 Faraday's Law and Lenz's Law | General Physics

[@spencerbybee8394]

Chad, I want to thank you for your dedication and continual uploads of priceless education to students. You really are blessing mine, and so many other student's lives. Prepping for a physics exam today and this video dropped just in time. I plan on buying your DAT prep course because of your great teaching skills, and the spirit you bring to teaching. God bless and thank you again!

Glad the video helped - hope you do well on your exam!

Hello sir, in 30:20 , wouldn't cos theta be negative here (if area vector is out of the board and B is into the board ) so as area is increasing, the flux is becoming more negative, and so (its magnitude is increasing),then emf is (-ve)×(-ve) is (+ve) ,is anti clockwise (if we consider the sign convention,that a positive emf is created by an anti clockwise current )

Yooo Chad! I had no idea that you were doing physics too! Will watch the playlist rn! Thanks!

[@ChadsPrep]

You're welcome and Happy Studying!

In a static magnetic field, when there is a change in the area of the loop, the change of magnetic flux has no effect. There is a motional emf in the loop due to the motion of the conductor through the magnetic field.
