Abstract
Provided is a low magnetic field and ultra-low magnetic field NMR and MRI apparatus. The low magnetic field and ultra-low magnetic field NMR and MRI apparatus includes a SQUID sensor and a prepolarization magnetic field coil. The prepolarization magnetic field coil generates a prepolarization magnetic field to polarize a sample. The prepolarization magnetic coil generates a counter pulse in a direction opposite to that of the prepolarization magnetic field immediately before or immediately after the prepolarization magnetic field is generated. The counter pulse demagnetizes wanted magnetization including that of the prepolarization magnetic field coil itself.
