Define magnetic field strength B as magnetic flux density

  • Strength of magnetic field (B) is known as magnetic flux density.
  • Flux is defined as rate of flow. For magnetic fields, this is the amount in a given area.
  • Measured in Tesla (T) or Weber per area squared (Wb/m2).
  • Stronger fields are represented by closer lines.
  • ϕB is used for notation.
