Both magnetization and magnetic intensity have the same unit.(a) True(

1.	Both magnetization and magnetic intensity have the same unit.(a) True(b) FalseThe question was asked in quiz.I would like to ask this question from Magnetisation and Magnetic Intensity topic in portion Magnetism and Matter of Physics – Class 12
Answer» Right choice is (a) True The best explanation: Both MAGNETIZATION and magnetic intensity have the same unit ➔ A/m. Magnetic intensity (H) = \(\frac {B_o}{\mu_o}\)B = \(\frac {current}{length}\) (ampere circuital LAW) ➔ unit of B0 = \(\frac {A}{m}\); μ0 is DIMENSIONLESS as it is a constant. THEREFORE, the unit of H is the same as B0. Magnetization (I) = \(\frac {M}{V}\)I = \(\frac {Magnetic \, moment}{Volume}\) ➔ Unit of magnetic moment = Am^2; Unit of volume = m^3; I = \(\frac {Am^2}{m^3} = \frac {A}{m}\) Thus, the units of magnetization and magnetic intensity is the same.
