Magnetic susceptibility ( χ ) is a material property indicating a material’s tendency to interact with and distort an applied magnetic field...

... an uncertainty of 1.5 % RSD. KEYWORDS: carbon brush, metals, FAAS, gravimetry, titremetry, XRD Introduction Carbon brush is a composite material, used in electrical contacts for ac/dc electric motors and in the rotating parts of electrical machines, which can withstand temperatures up to 3000° C. A carbon brush...
