The permeability of a metal is $0.1256 TmA^{- 1}$ . Its relative permeability will be $(\frac{μ _{0}}{4 π} = 1 0^{- 7}$ SIunit $) (π = 3.14)$

Options:

Answer:

Solution:

$μ = 0.1256 μ_{0} = 4 π \times 1 0^{- 7} = 4 \times 3.14 \times 1 0^{- 7} = 12.56 \times 1 0^{- 7} TmA^{- 1} μ_{r} = \frac{μ}{μ _{0}} = \frac{0.1256}{12.56 \times 1 0 ^{- 7}} = 1 0^{5}$
