Practice question

**Magnetic dipole moment** quantifies strength and orientation of magnet, m = 2l × q_m where q_m pole strength. Field line concept visualizes B, with closed nature reflecting absence of magnetic monopoles, explaining non-intersection and continuity. Paramagnetic materials have a small positive susceptibility ( chi > 0 ), causing a slight enhancement of the magnetic field inside them due to the weak alignment of atomic magnetic moments with the external field. They are attracted to regions of stronger field strength. Substituting values gives Paramagnetic materials, which matches expected magnitude for this magnetic configuration, confirming dipole field dependence on m/r³ and torque relation τ = m B sinθ.
