• Electric Flux (ΦE)


  Measure the flow of the electric field through an area in space.
• Electric Displacement Field (D)


  Measure the flow of charged particle from an area or surface influenced by an electric field.
• Electric Displacement Flux (ΦD)


  Total electric displacement flux passing through a given surface

  how many charged particles were displayed by the influence of an electric field.
• 1. Magnetic Flux (ΦH)


  How much magnetic field lines are passing through the open area
• 1. Magnetic Flux (ΦB)


  How much magnetic field lines are passing through the open area.

  similar to the electric flux
• Maxwell's Equations


  A set of equations that describe the behavior of electromagnetic waves
• Maxwell published his work on the unified electromagnetic equations


  1861 to 1862
• Maxwell's Equations


  • They show the parallelism between the electric and magnetic quantities
  • They describe the behavior of electromagnetic waves
• Speed of light (c)


  Represented by the symbol 'c', which stands for the initial letter of the Latin word "celerity" meaning "swift" or "quick"
• Speed of light is approximately 3 x 10^8 m/s
• Electric field (E)


  Perpendicular to magnetic field (B)
• Maxwell’s Equations were originally based on :

  • Gauss’ Law
  • Faraday’s Law
  • Ampere’s Law
• Gauss' Law For Electricity

  • States that the electric flux through any closed surface is proportional to the net electric charge enclosed by that surfaced.
• A changing Magnetic Field Induces an Electric Field.
• The total Electric flux coming through or out a closed surface is proportional to the charge enclosed.
• There is no divergence for magnetic fields as these are closed loops.
• Electric Displacement Field (D) SI unit:

  C/m^2
• Electric Flux Si unit:

  Vm and Nm^2/C
• Electric Displacement Flux SI unit:

  C or Coulombs
• H-Magnetic Flux SI unit:

  Ampere-meter (Am)
• B-Magnetic Flux SI unit:

  Weber and Maxwell
