    Abstract: Provided are an ultra-low field nuclear magnetic resonance device and a method for measuring an ultra-low field nuclear resonance image. The ultra-low field nuclear magnetic resonance device includes an AC power supply configured to supply a current to a measurement target in such a manner the current flows to the measurement target, magnetic field measurement means disposed adjacent to the measurement target, and measurement bias magnetic field generation means configured to apply a measurement bias magnetic field corresponding to a proton magnetic resonance frequency of the measurement target. A vibration frequency of the AC power supply matches the proton magnetic resonance frequency of the measurement target, and the magnetic field measurement means measures a nuclear magnetic resonance signal generated from the measurement target.
