# a magnetism field of 2X10^3 Am-1 produces a magnetic flux density of 8 phi Tesla in an iron rod. the realative permeability of the rod will be10^210^010^110^4

relative permeability of rod is given by
ur = B/(uo*H)
H = 2*103 A/m
u0 = 4$\pi$*10-7
B = 8$\pi$
so,
ur = 104.
Hope it clears. If you like anser then please approve it.
