Electricity and Magnetism Principles

Core Concepts of Electromagnetism

• Resistance: A measure of how much a material opposes the flow of electric current and changes electric current into heat energy.
• Conductor: A material through which electric current passes easily.
• Insulator: A material through which electric current doesn't pass easily.
• Series Circuit: A circuit that connects several objects one after another so that the current flows in a single path.
• Parallel Circuit: A circuit that connects several objects in a way that the current for each object has its own path.
• Magnet: Anything that pulls iron, steel, and certain other metals to it.
• Magnetism: The force around a magnet.
• Magnetic Field: The space around a magnet where magnetism acts.
• Pole: The place on a magnet where magnetism is strongest.
• Compass: A small magnet that can turn freely.
• Generator: A machine that uses an energy source and a magnet to make electricity.
• Electromagnet: A magnet made when an electric current flows through a wire.
