Question

Which material has \( \chi \) slightly positive and moves from weaker to stronger field regions?

Options

Choose one · Correct answer highlighted

Explanation

**Paramagnetism** has small positive χ ≈ 10⁻³ to 10⁻⁵, weakly attracted towards stronger field, random moments align partially with B, magnetization decreases with temperature following Curie law χ ∝ 1/T. Materials have unpaired electrons with permanent moments. Paramagnetic materials have a small positive chi and are weakly attracted from weaker to stronger magnetic field regions. Substituting values gives Paramagnetic, which matches expected magnitude for this magnetic configuration, confirming dipole field dependence on m/r³ and torque relation τ = m B sinθ.
