Abstract
Provided are an object discrimination method and an object discrimination apparatus using an ultra-low magnetic field nuclear magnetic resonance (NMR). The method includes measuring the respective spin-lattice relaxation times at a plurality of strengths of prepolarization magnetic fields with respect to a measurement target and classifying the measurement target using the spin-lattice relaxation times.
