 the MRI uses a powerful electromagnetic field to align the nuclear magnetizations.
now, the machine uses Radiofrequency to almost “shake” the aligned nuclear magnetization, and just like when you pass a magnet through a coile the movment or vibrations produce a tiny magnetic field in each atom that the scanner can detect and from that creates an image
