Liquids and gases never show ferromagnetic property. The ferromagnetic materials are those substances which exhibit strong magnetism in the same direction of the field when a magnetic field is applied to it. Ferromagnetic materials, such as iron contain unpaired electrons, each with a small magnetic field of its own, that align readily with each other in response to an external magnetic field. This alignment tends to persist even after the magnetic field is removed. In case of liquids and gases, there will be more randomness in magnetic moments and will fail to align in one direction.
