Finally, the understanding of the magnetic properties of bulk magnets can facilitate the engineering of better-performing magnets through the manipulation of atomic-scale defects and chemistry. The magnetic fluids have a wide range of applications in chemical engineering, technological processes, and devices such as sensors, attenuating mechanisms, printers, and acoustic radiators. Additionally, magnetic nanoparticles functionalized with relevant biomolecules have shown potential as contrast agents for magnetic resonance imaging and have demonstrated bioactivity, making them excellent candidates for applications in nanomedicine or nanobiotechnology. These materials can be used in real engineering applications due to their ability to alter their moduli when exposed to an external magnetic field. MREs, on the other hand, are particulate composites that change their mechanical and rheological properties in the presence of a magnetic field. Nanoparticles can be engineered to have specific electronic, optical, magnetic, mechanical, thermal, vibrational, and surface properties, which allow them to be used in various fields such as medicine, cosmetology, engineering, food packaging, and bioprocessing.
