This questions was previously asked in

EPFO AO EO 2017

Nitrogen

Sodium chloride

Water

Iron

- Diamagnetic materials weakly repel external magnetic fields and have no net magnetic moments per atom.

- Option 1: Nitrogen - Diamagnetic, as gas molecules exhibit slight magnetic field resistance.

- Option 2: Sodium chloride - Diamagnetic, having neutral atomic centers that weakly repel magnets.

- Option 3: Water - Diamagnetic, due to its electronic structure that opposes an external field.

- Option 4: Iron - Correct. Iron is not diamagnetic; it is ferromagnetic and strongly attracted by magnetic fields.
