Electromagnetism Units

Symbol Units Name Definition
Flux A scalar value. The rate of transfer of energy (or another physical quantity) per unit area. <ref> Wiktionary - Flux </ref>
Electric field (intensity/strength) The space surrounding an electric charge. It will exert a force on other electrically charged objects.
Electric (flux density/displacement field) The amount of electric flux in a unit area perpendicular to the direction of electric field
Magnetic field (intensity/strength) A magnetic field is a vector field which surrounds magnets and electric currents, and is detected by the force it exerts on moving electric charges and on magnetic materials. <ref> Magnetic field </ref>
Magnetic (flux density/induction) The amount of magnetic flux in a unit area perpendicular to the direction of magnetic flow
Electric field lines <ref> Electric field lines</ref>
Electric flux density <ref> Electric flux density </ref>

Analogies between Electric & Magnetic Circuits

Electric Magnetic Notes
Kirchoff's voltage law, Ampere's law
Kirchoff's current law, The B-field has to go around in a loop
Magnetic flux, Phi
Reluctance
or Assumes linearity - exceptions: Hysterisis loop, etc
