Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the discoverer?Michael Faraday
2. What is the core phenomenon?Electromagnetic induction: a changing magnetic flux induces an electromotive force (EMF)
3. How does a changing magnetic field create electricity?A changing magnetic field changes the magnetic flux through a loop of wire. That change makes an electric field curl around the loop, which drives current.
4. What is the difference between transformer EMF and motional EMF?Transformer EMF happens when the magnetic field itself changes, while motional EMF happens when a conductor moves through a magnetic field. In reality, they are just two ways of seeing the same effect depending on the observer.

Maxwell-Faraday Equation: A fundamental equation in electromagnetism describing how changing magnetic fields induce electric fields.
Magnetic Flux: A measure of the total magnetic field lines passing through a given surface area.
Lenz's Law: States that the direction of an induced current opposes the change in magnetic flux that produced it.
