Intensity of magnetization

  • Intensity of magnetization is denoted by I
  • It represents the extent to which the material is magnetized
  • When we place a material in the magnetic field , atomic dipoles of the material tends to align fully or partially in the direction of the field.
  • So, the net magnetic moment is developed in the direction of the field in any small volume of the material.
  • Intensity of magnetization is defined as the magnetic moment per unit volume of the magnetized material. So, I=M/V , where M is the total magnetic moment within volume V due to the magnetizing field i.e., M=∑ m
  • Unit of I is Am-1
