WebSince M is precessing, in general M z and M xy will be a function of time. The net magnetization (M) is a vector that can be resolved into components longitudinal (Mz) and transverse (Mxy) with respect to the main magnetic field (Bo). At rest (between imaging sequences) M is aligned with Bo and hence Mz = Mo us a maximum and Mxy=0. WebMagnetization refers to magnetizing a magnetic substance or increasing the magnetism of a magnet with insufficient magnetism. Generally, the magnetic object to be magnetized is …
