Paramagnetic materials

Paramagnetic materials are substances that are weakly attracted to magnetic fields because they contain unpaired electrons in their atoms or molecules. These unpaired electrons have magnetic moments that align partially with an external magnetic field, causing a slight attraction. Unlike ferromagnetic materials (like iron), paramagnetic materials do not retain magnetization once the external field is removed. Examples include aluminum and platinum. Their magnetic response is typically weak and only noticeable when exposed to strong magnetic fields, making them useful in applications like magnetic resonance imaging (MRI) and scientific measurements.
