Introduction When exploring the magnetic properties of materials, understanding paramagnetic vs. diamagnetic vs. ferromagnetic behavior is essential. These terms describe how materials respond to external magnetic fields. Paramagnetic materials, such as aluminum and oxygen, weakly attract magnetic fields due to unpaired electrons. In contrast, diamagnetic materials, including copper and bismuth, exhibit weak repulsion as their electrons are paired, canceling magnetic moments. Ferromagnetic materials like iron, cobalt, and nickel strongly attract and retain magnetism, making them essential in permanent magnets and electronic devices. Comparing paramagnetic vs. diamagnetic vs. ferromagnetic properties reveals the diverse ways materials interact with magnetic fields, influencing applications…
