//Given Values:
u0=4*%pi*10^-7 //Permeability in vacuum
A=0.2*10^-4 //Crosss sectional area of iron bar in m^2
H=1600 //magnetising field in A/m
phi=2.4*10^-5 //Magnetic flux in weber
//Calculations:
//We know, phi=B*A
B=phi/A //Flux density
u=B/H //magnetic permeability
ur=u/u0 //relative permeability
xm=ur-1 //susceptibility of the iron bar
printf('magnetic permeability of iron bar is =%.6f N/(A^2) \n \n',u)
