Study Notes
Magnetic Materials
- Diamagnetic materials are characterized by the absence of a permanent dipole moment, and the induced moment produced decreases the magnetic induction.
- When placed in an external magnetic field, induced dipoles in diamagnetic materials are aligned opposite to the external field.
- The magnetic susceptibility of diamagnetic materials is negative.
- The degree of magnetization in magnetic materials is characterized by the magnetic permeability.
- A material with no spin or magnetic moment is classified as diamagnetic.
