A method for making moldable and cuttable composite material for magnetic moment calibration of samples with specific shapes is provided. The method is used to quantify a magnetic moment per unit weight from the moldable and cuttable composite material. The moldable and cuttable composite material is made by a non-magnetic matrix with superparamagnetic particles, paramagnetic particles, or ferromagnetic particles without anisotropy. Then, the moldable and cuttable composite material is shaped and tailored into calibration samples with specific shapes. The method provides a method for making calibration samples with the specific shapes, wherein the calibration samples are easily shaped and tailored to same or similar shapes and sizes as test samples. The method improves an original method for making a standard calibration sample, wherein the original method only used pure nickel ball or high purity palladium wire structure.
