As susceptibility of a magnetic material is – 2.6 × 10-⁵, the material is a diamagnetic material. two important properties of these materials are: (i) These are feebly repelled by a magnetic field and tend to move from stronger to ...
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 ...
