MCQ
The basic magnetization curve for a ferromagnetic material is shown in figure. Then, the value of relative permeability is highest for the point
- A$P$
- ✓$Q$
- C$R$
- D$S$
✓
Answer
Correct option: B.
$Q$
(b) $B=\mu_0 \mu_r H \Rightarrow \mu_r \propto \frac{B}{H}=$ slope of $B$ - $H$ curve According to the given graph, slope of the graph is highest point $Q$.
