Networks Analysis and Synthesis

Q1: 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

A 0.6 T

B more than 0.6 T

C less than 0.6 T

D 0.6 T or less than 0.6 T

ANS:D - 0.6 T or less than 0.6 T

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