Question

The figure gives experimentally measured $B$ vs. $H$ variation in a ferromagnetic material. The retentivitv, co-ercivity and saturation, respectively, of the material are:

• A. $1.5 \,T, 50 A /m$ and $1.0 \,T$
• B. $1.0 \,T, 50 A/m$ and $1.5\, T$
• C. $1.5\, T, 50 A/m$ and $1.0\, T$
• D. $150\, A /m , 1.0 \,T$ and $1.5 \,T$

Answer 1

Answer: (B)

Retentivity = 1.0 T
Co-ercivity = 50 A/m
Saturation = 1.5 T
