Electromagnetism

  • Intimate relationship between electricity and magnetism
  • Theory of electromagnetism developed by James Clark Maxwell
    • Deals with particles electric charges and their effects, especially when they are moving
  • Electric and magnetic field changes --> trigger each other
    • Changing magnetic fields can produce electric currents
      • Changing electric fields
    • Changing electric fields can produce changing magnetic fields

Electromagnetic Waves

  • Can move through a vacuum
    • The aether was made up in the nineteenth century because scientists couldn't grasp the fact that these waves can move in a vacuum
  • All electromagnetic waves move at the same speed in empty space
