Describe how magnetic flux can change

Describe how magnetic flux can change

  • Magnetic flux is the amount of magnetic field passing through an area (A) perpendicular to a uniform magnetic field (B).
  • The flux passing through the area is denoted by ф
    • magnetic-flux
    • magnetic-flux-2
    • ф varies by how the area is oriented to the magnetic field lines.


  • direction
    • The “direction” of the area is considered as the direction perpendicular to it.
  • Hence if the magnetic field lines are passing perpendicularly through the area A, it is actually in the same direction as the area
