Which of the following property is associated with paramagnetic solid substances?

They are weakly attracted by external magnetic field

Paramagnetism: Paramagnetic substances are weakly attracted by a magnetic field. They are magnetised in a magnetic field in the same direction. They lose their magnetism in the absence of magnetic field. Paramagnetism is due to presence of one or more unpaired electrons which are attracted by the magnetic field. O₂, Cu²⁺, Fe³⁺, Cr³⁺ are some examples of such substances.
