H IS INTENSITY OF MAGNETIC FIELD
B IS MAGNETIC FIELD INDUCTION
H=B IN C.G.S SYSTEM
BUT....,
B=uoH
H= m / (4pi r^2)
H =B/uo
hai sr i know very little much sir.
Based on Maxwell''s equations, electric fields are generated by changing B fields, while H fields are generated by changing electric fields. In dc fields, static electric E fields create currents (magnetization currents) I (when σ>0) which in turn produce static H fields. A static B field (actually d/dt ∫B·n dA = 0) cannot produce an electric field E. Even if we used natural units where μ0 = ε0 = 1, this distinction between B and H remains. In magnetic materials, B is not linearly related to H due to the magnetization term M. If B = H in space, then B ≠ H in magnetic materials.
