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.

Abstract: Provided are an ultra-low-field nuclear magnetic resonance device and an ultra-low-field nuclear magnetic resonance measuring method. The method includes applying a first measurement bias magnetic field corresponding to an excitation frequency of a coherent biomagnetic field generated in association with the electrophysiological activity of human body organs, applying a second measurement bias magnetic field having the same direction as the first measurement bias magnetic field and having a different magnitude than the first measurement bias magnetic field, and measuring a magnetic resonance signal generated in the human body by using magnetic field measuring means.
