Einstein-de Haas Effect
Introduction The Einstein-de Haas effect is a physical phenomenon that demonstrates the connection between the angular momentum and the magnetic moment of a ferromagnetic material. It provides experimental evidence for the idea that spin angular momentum is indeed of the same nature as the classical angular momentum. The Basic Principle of the Einstein-de Haas Effect…

Larmor Precession
Introduction Larmor precession is a phenomenon observed in quantum mechanics, where the spin (or magnetic moment) of a particle precesses around an external magnetic field. This principle is fundamental to technologies like magnetic resonance imaging (MRI) and nuclear magnetic resonance (NMR) spectroscopy. Basic Principle of Larmor Precession A magnetic moment in an external magnetic field…

Magnetism
Introduction Magnetism is a physical phenomenon produced by moving electric charge that results in attractive and repulsive forces between objects. It is one aspect of the combined electromagnetic force and shares many similarities with electricity, which is why they are usually thought of together as electromagnetism. Magnetic Fields and Magnetic Force Magnetic fields are a…

Zeeman Effect
Introduction The Zeeman Effect, named after the Dutch physicist Pieter Zeeman, is the splitting of a spectral line into several components in the presence of a static magnetic field. It is a key phenomenon in atomic physics and quantum mechanics that illustrates the interaction between magnetic fields and the magnetic moments of atoms. Understanding the…
