Question
In a specimen of silicon steel, a field strength of 200 A/m causes a flux density of 0.5 T. In a specimen of cast iron, the same H would cause B to be
Options
A. 0.5 T
B. less than 0.5 T
C. more than 0.5 T
D. 0.5 T or more or less

Correct Answer

less than 0.5 T

Explanation

Because cast iron has lower permeability than silicon steel.
