Learn what Faraday's law means and how to use it to determine the induced electro-motive force.

Faraday's, Faraday's Law. And we'll quantify this more in future videos but it's just the notion that if I have a loop of wire and I have a changing magnetic flux through the loop of wire, that is …

Electrolysis equation: I = Q t Electrolysis variables and constants: I = current (amperes) Q = charge (coulombs) t = time (seconds) Faraday’s constant, F = 96,485 coulombs per mole = …

When the magnetic flux through a conducting loop changes, current is induced in the loop. This current produces it's own magnetic field. Lenz's law tells us that the current flows in the …

Learn what magnetic flux is, how to calculate it, and how it relates to Faraday's law.

Practice Faraday's law - magnitude of induced emf (average) Get 3 of 4 questions to level up!

Now the next question we should ask ourselves and this is where this little negative comes in, is a reminder for us to use Lenz's law is, well which direction is that current going to go in?

It’s covered in the article directly before this video in the AP Physics 2 course. The article is called “Magnetic flux and Faraday’s law.”

Is it possible to produce electric current without using batteries? Let's find out.
