  2. The given material is diamagnetic, as its susceptibility is negative (– 2.6 × 10-⁵). Two important properties are: (i) Diamagnetic materials are feebly repelled by a magnetic field and move from stronger to weaker field regions. (ii) Their individual atoms have zero magnetic dipole moment. For moreRead more

    Magnetic susceptibility (χ) measures a material’s ability to be magnetized in an external magnetic field. Copper, a diamagnetic material, has negative susceptibility, while aluminum, a paramagnetic material, has positive susceptibility. Negative susceptibility signifies that the material is repelled by a magnetic field, expelling magnetic field lines from within it.
