//Variable declaration
I=3000; //magnetisation(amp/m)
mew0=4*%pi*10**-7;
B=0.005; //flux density(weber/m**2)
//Calculation
H=(B/mew0)-I; //magnetizing force(amp/m)
mewr=(I/H)+1; //relative permeability
//Result
printf("magnetizing force is %.3f Amp/m",H)
printf("\n relative permeability is %.3f",mewr)
//answer in the book varies due to rounding off errors
