Watch the following videos on the electric field induced by a changing magnetic field. Before watching though, think about the following situation. So we know by F = qv x B that a MOVING charge in a magnetic field feels on a force and can be made to move. Let's say we have a loop sitting in a constant magnetic field at first. The charges sitting in the loop are not moving - even though these charges are in a magnetic field, there are no forces on the charges because their velocity is zero. But as soon as we try to change that magnetic field, all of a sudden, the charges start to move - a current is induced. That implies that there is a FORCE on those charges causing them to accelerate from REST. Where does that force come from? Can it be a magnetic force dictated by F = qv x B? If not, what kind of force is it? Seriously think about these questions! Now watch the videos.

❀️ 1: T 3/22, πŸ’› 3: M 3/21 - general form of Faraday's Law

Today, we'll start with a brief discussion about the general form of Faraday's Law.

Then, we'll continue doing some practice problems using the "general form of Faraday's Law."

Required: 1985E3, 1996E3, 1999E2

Watch the following video on transformers first, and then read the "Transformer: Basic Principles" section from Wikipedia to understand the derivation of the ideal transformer equation. You must be able to apply the "ideal transformer equation" with which you should already be familiar from last year.

The ideal transformer equation:
