As the susceptibility of given magnetic material (x = – 4.2 × 10⁻⁶) is extremely small but negative, the materials is a diamagnetic material. Class 12 Physics Chapter 5 Magnetism and Matter Session 2024-2025.
As the susceptibility of given magnetic material (X = 1.9 ×10⁻⁵) is extremely small but positive, the materials is a paramagnetic material. Class 12 Physics Chapter 5 Magnetism and Matter Session 2024-2025.
No, diamagnetic substances do not have a resultant magnetic moment in an atom in the absence of an external magnetic field because their electron pairs have opposite spins, canceling out. Class 12 Physics Chapter 5 Magnetism and Matter Session 2024-2025.
