The total magnetic moment of an electron, a key concept in Quantum Mechanics and Atomic Physics, is the measure of the electron's magnetic dipole moment. It is influenced by the electron's orbital and spin angular momenta. Calculating the total magnetic moment involves important variables such as the Landé g-factor, total quantum numbers, and the Bohr magneton.

The total magnetic moment of an electron is given by the following formula:
Where:
The calculation of the total magnetic moment of an electron was refined with the introduction of quantum mechanics, specifically through the work of Alfred Landé who introduced the Landé g-factor. This formula is integral to the Quantum Theory of Angular Momentum and the Zeeman Effect.
This calculation plays a significant role in Magnetic Resonance Imaging (MRI), a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. It helps in producing the contrast in the images, which allows medical professionals to distinguish between different types of tissues.
Alfred Landé, a German-American physicist, is renowned for his contributions to quantum theory, specifically the introduction of the Landé g-factor. Niels Bohr, a Danish physicist, also made significant contributions to atomic physics and quantum theory, including the concept of the Bohr magneton.
The total magnetic moment of an electron is a fundamental concept in Quantum Mechanics and Atomic Physics. It continues to hold significant theoretical interest, while its practical implications, as seen in technologies like MRI, underscore its importance in our daily lives. It stands as an exemplar of the powerful insights quantum theory can provide into the microscopic world.
