The equation of the magnetic field intensity is given as Where represents density of magnetic flux, represents magnetic permeability, represents the magnetization
The Magnetic Field Intensity or Magnetic Field Strength is a ratio of the MMF needed to create a certain Flux Density (B) within a particular material per unit length of that material.
It's expressed as the vector and measured in amperes per metre.
The SI unit of the magnetic field is tesla
Magnetic field intensity helps us to measure the strength of the magnetic field intensity.
