Two samples of linear magnetic material are measured at room temperature. Sample A has magnetic susceptibility χm=+2.7×10−4 and sample B has χm=−1.66×10−4.
((a)) Find the relative permeability of sample A, to six significant figures.
((b)) Find the relative permeability of sample B, to six significant figures.
((c)) Find the permeability μ of sample A, in TmA−1, to five significant figures.
