Module 3 : MAGNETIC FIELD
Lecture 20 : Magnetism in Matter
\begin{displaymath}B = \mu_0(nI+M)\end{displaymath}

  In analogy with the way we introduced displacement vector $\vec D$ to account for the effect of a dielectric in electrostatics, we introduce a new field, which we will call H-field
 
\begin{displaymath}\vec H = \frac{\vec B}{\mu_0}-\vec M\end{displaymath}
