How Do the Units Work With Faraday’s Law?

Image: Rhett Allain. My original work on this calculation.

Faraday’s Law is sort of a big deal. It says that a changing magnetic flux creates an electric field. This electric field then creates a change in electric potential around a closed loop (we often call this an electromotive force — EMF). As an equation, it looks like this.

Oh wait! What about the negative sign? OK, I’m not a huge fan of the negative sign in this equation since it’s sort of…
