Diamagnetic materials are substances that are weakly repelled by a magnetic field because their electrons, which are all paired, rearrange their paths to create an opposing magnetic field. This creates a small, negative magnetic susceptibility. Common examples include water, copper, gold, and most organic molecules.
Diamagnetism occurs in atoms and molecules where all electrons are paired, meaning their magnetic fields cancel each other out.
Induced Field:
When an external magnetic field is applied, the electrons in the diamagnetic material slightly change their orbits.
Opposing Force:
. This change creates a tiny, induced magnetic field within the material that is in the opposite direction of the applied field, resulting in a weak repulsive force.
Negative Susceptibility:
. Diamagnetic materials have a negative magnetic susceptibility, meaning they are repelled by a magnet.
Metals: Copper, silver, gold, and bismuth are diamagnetic.
Organic Compounds: Many organic molecules, including water, wood, and most living organisms, are diamagnetic.
Other Examples: Nitrogen, quartz, and diamonds also exhibit diamagnetic properties.
