Here, the main methods of measuring GnM using polarized and unpolarized electron-nucleon scattering at different accelerators are reviewed, emphasizing their techniques and challenges. Polarized measurements at low Q2 values using the transverse asymmetry AT' in the scattering of an electron by a Helium-3 nucleus are discussed, highlighting MIT-Bates's and Jefferson Lab experiments. Unpolarized measurements from SLAC experiments and recent CLAS data at higher Q2 are utilized to review various techniques, including inclusive quasielastic electron-deuterium scattering, coincidence quasielastic electron-neutron cross-section measurements, and anti-coincidence quasielastic electron-deuterium cross-section measurements. Additionally, the extraction of GnM is explored using the ratio of quasielastic electron-neutron to quasielastic electron-proton cross-section, highlighting its benefits in reducing systematic uncertainties and enhancing precision. The comparison of these methods to theoretical models showcases the complexities and advancements in understanding GnM, laying the foundation for future research in nucleon structure.
