For definition, see point number 23 under the heading “Chapter At Glance”.
Copper (a diamagnetic material) has negative susceptibility but aluminium (a paramagnetic material) has positive susceptibility.
Nagative susceptibility signifies that the material is repelled in a magnetic field and magnetic field lines are expelled from the material.

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.
