Answer #1

Question 2)

As seen from the diagram, HC = 200 A-t/m for silicon steel corresponding to BC = 1.0 T.

3) A soft-cast steel core that has a magnetic field intensity of 600 A-t/m in the material means it is in linear region. Since the curve for soft-cast steel core upto 1000 A-t/m is linear.

Therefore, the statement is false.

5) BC = \mu o \mu r HCC

\mur =1.1/ 260* 4* pi* 10-7 = 3367

6) A silicon steel for BC = 0.7 T is operating inthe linear region.

Therefore, the statement is true.
