Paramagnetism in Everyday Life

What is Paramagnetism?

Paramagnetism is a property of material by virtue of which, when a material is placed in a magnetic field, it gets weakly magnetized. The materials which exhibit paramagnetism are called Paramagnetic Materials. In such substances, the individual atoms or molecules have unpaired electrons, causing them to align with the external magnetic field. This alignment enhances the overall magnetic moment of the material, making it weakly attracted to the applied magnetic field. Unlike ferromagnetic materials, which retain their magnetization even after the field is removed, paramagnetic materials only exhibit magnetism in the presence of an external magnetic field. Common paramagnetic substances include oxygen and some metal ions. The magnetic response is relatively weak, and paramagnetism is often observed at room temperature....

Magnetic Moments in Paramagnetic Materials

Magnetic moments in materials occur due to the existence of unpaired electrons. In paramagnetic materials, the magnetic moments of individual atoms or ions do not align spontaneously in the absence of an external magnetic field. However, when an external magnetic field is applied, the magnetic moments tend to align with the field direction, leading to a net magnetization of the material....

Curie Law

Paramagnetism in Everyday Life

Paramagnetism is a property found in certain materials where individual atoms or molecules have magnetic moments that align with an external magnetic field. In everyday life, some common examples include aluminum, platinum, and oxygen. When exposed to a magnetic field, these materials become weakly attracted to it. While the effect is subtle, it has practical applications, such as in magnetic resonance imaging (MRI) machines used in medical diagnostics and certain electronic components like transformers....
