Diamagnetic

Diamagnetic describes a substance or material that exhibits diamagnetism, a form of magnetism where the material creates a magnetic field in opposition to an externally applied magnetic field. This effect is a quantum mechanical phenomenon arising from the interaction of the external field with the orbital motion of electrons within the atoms of the substance. Diamagnetism is a weak form of magnetism, and diamagnetic materials are repelled by a magnetic field. This repulsion occurs because the applied field slightly alters the electron orbits, inducing a magnetic dipole moment that opposes the external field. All materials exhibit diamagnetic behavior, but it's often masked by stronger magnetic effects if present.

Diamagnetic meaning with examples

• Graphene, a form of carbon, is known to be diamagnetic. When placed near a strong magnet, the graphene sheet subtly repels. This behavior is because the external magnetic field induces tiny circulating currents within the carbon atoms. These currents create a magnetic field that opposes the external field, a characteristic demonstrating its diamagnetic nature.
• Water is a diamagnetic substance. Consequently, it displays a weak repulsion from a magnet. You can observe this by carefully suspending a droplet of water near a powerful magnet. The water will experience a slight force pushing it away, a testament to the diamagnetic properties of its constituent molecules and how they react to the external field.
• Copper, along with other heavy metals, is diamagnetic. Consequently, when subjected to a magnetic field, a copper object will experience a slight, barely noticeable repulsion. This diamagnetic characteristic affects the behavior of the metal, and it will repel the magnetic field slightly because of the electron orbital shift induced by the field.
• Bismuth is a notably strong diamagnetic element. It is repelled by magnets more noticeably than many other materials. This behavior is due to the arrangement of electrons in its atomic structure. A bismuth object, therefore, experiences a stronger repulsive force compared to substances such as aluminum when put near a magnet, highlighting its diamagnetic qualities.
