  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[2]: You need a concise definition of an electromagnetism concept.,You are connecting circuit laws to the field laws behind them.
  caveats[2]: 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[16]{concept,description}:
  Electric Charge,Property producing electric force; positive or negative.
  Electric Field,Region around a charged particle where force is exerted.
  Magnetic Field,Region around a magnet or current where magnetic force acts.
  Coulomb's Law,Force between charges is proportional to product of charges and inversely proportional to distance squared.
  Ohm's Law,Current equals voltage divided by resistance.
  Electromagnetic Induction,Changing magnetic field induces an electric current.
  Electric Potential,Potential energy per unit charge at a point; its difference between two points is voltage.
  Gauss's Law,The electric flux through a closed surface is proportional to the enclosed charge.
  Faraday's Law,A changing magnetic flux through a loop induces an electromotive force in it.
  Lenz's Law,An induced current flows in the direction that opposes the change in flux that produced it.
  Ampere's Law,"A magnetic field circulates around an electric current, as Maxwell extended it, and around a changing electric field."
  Maxwell's Equations,Four equations that together describe how electric and magnetic fields arise from charges and currents and from each other.
  Capacitance,"The ability of a component to store charge per unit voltage, measured in farads."
  Inductance,"The property of a circuit element to oppose changes in current by storing energy in a magnetic field, measured in henries."
  Lorentz Force,"The force on a charge moving in electric and magnetic fields: F = q (E + v x B)."
  Electromagnetic Wave,A self-propagating oscillation of electric and magnetic fields that travels at the speed of light in vacuum.
