diamagneettisesti

Diamagneettisesti refers to the magnetic properties of a material that is weakly repelled by an external magnetic field. This phenomenon, known as diamagnetism, occurs in all materials, but it is often masked by stronger paramagnetic or ferromagnetic effects. In diamagnetic materials, the applied magnetic field induces a magnetic dipole moment that opposes the field, leading to a net repulsive force. This induced magnetic moment arises from changes in the orbital motion of electrons within the atoms. When an external magnetic field is applied, it alters the orbital motion of the electrons in such a way that they generate a magnetic field that counteracts the applied field. The strength of this induced field is proportional to the applied field, and the proportionality constant is known as the magnetic susceptibility, which is negative for diamagnetic materials. Common examples of diamagnetic materials include water, bismuth, copper, and most organic compounds. Diamagnetism is a quantum mechanical effect and is present in all substances, though its magnitude is typically very small. In everyday life, diamagnetic effects are usually too weak to be observed without sensitive equipment. However, in some specific applications, such as magnetic levitation of diamagnetic materials, these properties can be utilized.
