  title: Electromagnetism Basics
  description: Fundamental concepts in electromagnetism.
  summary: "The basic concepts of electricity and magnetism: charge, electric and magnetic fields, Coulomb's law, Ohm's law and electromagnetic induction, plus Gauss's law, Faraday's law, Maxwell's equations, capacitance, inductance, the Lorentz force and electromagnetic waves."
  use_when:
    - You need a concise definition of an electromagnetism concept.
    - You are connecting circuit laws to the field laws behind them.
  caveats:
    - Ohm's law describes ohmic materials and is not a fundamental law; many components are non-ohmic.
    - Equations of electromagnetism have different forms in SI and Gaussian units.

data:
  - concept: Electric Charge
    description: Property producing electric force; positive or negative.
  - concept: Electric Field
    description: Region around a charged particle where force is exerted.
  - concept: Magnetic Field
    description: Region around a magnet or current where magnetic force acts.
  - concept: Coulomb's Law
    description: Force between charges is proportional to product of charges and inversely proportional to distance squared.
  - concept: Ohm's Law
    description: Current equals voltage divided by resistance.
  - concept: Electromagnetic Induction
    description: Changing magnetic field induces an electric current.
  - concept: Electric Potential
    description: Potential energy per unit charge at a point; its difference between two points is voltage.
  - concept: Gauss's Law
    description: The electric flux through a closed surface is proportional to the enclosed charge.
  - concept: Faraday's Law
    description: A changing magnetic flux through a loop induces an electromotive force in it.
  - concept: Lenz's Law
    description: An induced current flows in the direction that opposes the change in flux that produced it.
  - concept: Ampere's Law
    description: A magnetic field circulates around an electric current, as Maxwell extended it, and around a changing electric field.
  - concept: Maxwell's Equations
    description: Four equations that together describe how electric and magnetic fields arise from charges and currents and from each other.
  - concept: Capacitance
    description: The ability of a component to store charge per unit voltage, measured in farads.
  - concept: Inductance
    description: The property of a circuit element to oppose changes in current by storing energy in a magnetic field, measured in henries.
  - concept: Lorentz Force
    description: "The force on a charge moving in electric and magnetic fields: F = q (E + v x B)."
  - concept: Electromagnetic Wave
    description: A self-propagating oscillation of electric and magnetic fields that travels at the speed of light in vacuum.
