37.
In a specimen of cast iron, a field strength of 400 AT/m cause a flux density of 0.6 T. In a specimen of silicon steel, the same value of H would cause B to be
0.6 T
more than 0.6 T
less than 0.6 T
0.6 T or less than 0.6 T
Answer: Option
Explanation:

Since μr for silicon steel is more than that of cast iron, flux density will be more than 0.6 T.
