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)$B = {\mu _0}{\mu _r}H \Rightarrow {\mu _r} \propto \frac{B}{H}$= slope of $B- H $ curve
According to the given graph, slope of the graph is highest point $Q.$
(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 $Q.$
