Electricity & Magnetism Study Guide

These flashcards cover key terms and concepts related to electricity and magnetism as outlined in the study guide.

Electric Force

The force of attraction or repulsion between charged objects.

Electric Field

A region around a charged particle where a force would be exerted on other charges.

Conduction

The transfer of electric charge through a material by direct contact.

Induction

The process of charging an object without direct contact.

Friction

The transfer of electric charge through the rubbing of two objects together.

Conservation of Charge

The principle that the total electric charge in an isolated system remains constant.

Static Electricity

An accumulation of electric charge on an object.

Electric Current

The flow of electric charge in a conductor.

Ampere (Amp)

The unit of measurement for electric current.

Voltage

The electric potential difference between two points.

Resistance

The opposition to the flow of electric current.

Circuit

A closed path through which electric current flows.

Series Circuit

A circuit in which the components are connected in a single path.

Parallel Circuit

A circuit in which the components are connected across common points, creating multiple paths.

Magnet

An object that produces a magnetic field.

Magnetic Poles

The regions at the ends of a magnet where the magnetic force is strongest.

Magnetic Force

The attraction or repulsion between magnetic poles.

Magnetic Fields

Regions around a magnet where magnetic forces can be detected.

Electromagnet

A type of magnet made by passing an electric current through a coil of wire.

Ohm’s Law

The relationship between voltage, current, and resistance in a circuit.

Solenoid

A coil of wire that produces a magnetic field when electrical current passes through it.
