Question

The magnetic property inherent in all materials is

• A. para-magnetism
• B. ferro-magnetism
• C. dia-magnetism
• D. non-magnetism

Answer 1

The correct option is C dia-magnetism

Diamagnetism is the property of an object which causes it to create a magnetic field in opposition to an externally applied magnetic field, thus causing a repulsive effect. Specifically, an external magnetic field alters the orbital velocity of electrons around their nuclei, thus changing the magnetic dipole moment According to Lenz's law this opposes the external field. Diamagnets are materials with a permeability less than ${\mu }_0($a relative permeability less than $1)$.
