(a) For definition of magnetic susceptibility, see Point Number 23 under the heading “Chapter At A Glance”. Magnetic susceptibility X = u^r – 1, where u^r is the relative permeability of given material. (b) The magnetic materials A, whose relative ...
The material A, whose relative permeability is slightly greater than one, is a paramagnetic material. its susceptibility is positive. The material B, whose relative permeability is slightly less than unity, is a diamagnetic material. its susceptibility is negative. Class 12 ...
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 ...
(i) Diamagnetic substances, when placed in a non-uniform magnetic field, tend to move from stronger region of the field to the weaker region. On the other hand, paramagnetic substances move from weaker region of the field to the stronger region.
Here B = 0.02 T, θ = 30° and t = 0.060 N m (i) ∴ Magnetic moment of the magnet m = t/Bsinθ = 0.060/0.02 × 0.5000 = 6 A m² . (ii) For stable equilibrium of the magnet ...
The meterial is a diamagnetic material and its magnetic susceptibility x = u^r – 1 = 0.5 – = – 0.5 Class 12 Physics Chapter 5 Magnetism and Matter Session 2024-2025.
A superconductor behaves as an ideal diamagnetic substance. Hence, it moves away from the bar magnet when it is placed near the bar magnet. Class 12 Physics Chapter 5 Magnetism and Matter Session 2024-2025.
