Electricity Induction and Electromagnetic Theory

These flashcards cover key concepts and definitions related to electricity induction and electromagnetic theory from the lecture notes.

Faraday’s Law of Induction

A basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF).

Lenz's Law

States that the direction of induced electromotive force (emf) opposes the cause of its production.

Electromagnetic Induction

The production of an electromotive force across an electrical conductor in a changing magnetic field.

Self-Induction

The phenomenon where a changing current through a coil induces an electromotive force in the coil itself.

Inductance (L)

The property of a coil that quantifies its ability to induce an emf when the current changes.

Fleming’s Right-Hand Rule

A rule used to determine the direction of force in an electric generator, relating magnetic field, current, and mechanical force.

Electric Generator

A device that converts mechanical energy into electrical energy by utilizing electromagnetic induction.

Transformer

An electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

Electromotive Force (EMF)

The electrical action produced by a non-electrical source, measured in volts.

Flux (Φ)

A measure of the quantity of magnetism, taking into account the strength and extent of a magnetic field.
