Paramagnetism Examples

Paramagnetism Examples

Paramagnetism occurs due to the presence of unpaired electrons in the atoms or molecules of certain materials. These unpaired electrons align with an external magnetic field, causing a weak attraction between the substance and the magnet. Let’s take a closer look at some fascinating examples of paramagnetic materials:

1. Oxygen (O2)

Paramagnetism is most commonly observed in oxygen gas (O2). Each oxygen molecule contains two unpaired electrons, making it susceptible to alignment with an external magnetic field. While the paramagnetic effect in oxygen is relatively weak, it plays a crucial role in various applications, such as magnetic resonance imaging (MRI) and oxygen concentrators.

2. Aluminum (Al)

Aluminum is another classic example of a paramagnetic material. Although it contains no unpaired electrons in its ground state, it becomes paramagnetic at low temperatures due to the incomplete filling of energy levels. This property makes aluminum suitable for various industrial and technological applications, including magnetic storage media and electrical conductors.

Copper is known for its excellent electrical conductivity, but it also exhibits paramagnetic behavior. At low temperatures, copper displays paramagnetic properties due to the presence of unpaired electrons. This property is essential in electronics and power generation industries.

4. Titanium (Ti)

Titanium is a lightweight and strong metal commonly used in aerospace and medical applications. At low temperatures, titanium showcases paramagnetic behavior, offering valuable insights into its magnetic properties and potential applications in magnetic technologies.

5. Lithium (Li)

Lithium, an alkali metal, is paramagnetic due to its unpaired electron configuration. This property is vital in lithium-ion batteries, where the alignment of magnetic fields can influence battery performance and efficiency.

6. Platinum (Pt)

Platinum, a precious metal, exhibits paramagnetism at low temperatures. This property is exploited in various scientific experiments and industrial applications, including its use in magnetic instruments and laboratory equipment.

7. Nitrogen Dioxide (NO2)

Nitrogen dioxide is a paramagnetic gas commonly found in vehicle emissions and industrial processes. Its paramagnetic properties make it relevant in atmospheric and environmental studies, helping researchers analyze air pollution levels.

8. Gadolinium (Gd)

Gadolinium is a rare earth element used as a contrast agent in MRI scans due to its strong paramagnetic effect. It enhances the visibility of internal body structures, aiding medical professionals in diagnosing various health conditions.

9. Chromium (Cr)

Chromium displays paramagnetic behavior, which is useful in stainless steel production and various alloy applications. This property contributes to the durability and versatility of stainless steel.

10. Manganese (Mn)

Manganese is a transition metal that exhibits paramagnetism in its solid form. This property is crucial in various industrial applications, including steel production and battery manufacturing.

Paramagnetism vs. Diamagnetism and Ferromagnetism

Before diving deeper into more paramagnetism examples, let’s distinguish between paramagnetism, diamagnetism, and ferromagnetism. These three types of magnetism display distinct behaviors in the presence of an external magnetic field.


As discussed earlier, paramagnetism occurs in materials with unpaired electrons. When exposed to an external magnetic field, these materials align their magnetic moments in the direction of the field, resulting in a weak attraction to the magnet.


Diamagnetism, on the other hand, is observed in materials with all paired electrons. When subjected to an external magnetic field, diamagnetic materials generate a magnetic field opposing the external one, leading to a weak repulsion from the magnet.


Ferromagnetism is the most well-known form of magnetism, observed in materials like iron, cobalt, and nickel. Unlike paramagnetic and diamagnetic materials, ferromagnetic substances retain their magnetization even after the removal of an external magnetic field.
