Paramagnetic Materials
Paramagnetic materials are substances that are weakly attracted to a magnetic field. This attraction is due to the presence of unpaired electrons in the atoms or molecules of the material. When a paramagnetic material is placed in a magnetic field, the unpaired electrons align their magnetic moments with the external field, causing the material to be attracted to the magnet.
Properties of Paramagnetic Materials:
- Weak attraction to magnetic fields
- Presence of unpaired electrons
- Do not retain magnetization when the external magnetic field is removed
- Examples of paramagnetic materials include aluminum, platinum, and oxygen
Study Guide:
- What are paramagnetic materials?
- What causes the weak attraction of paramagnetic materials to magnetic fields?
- Why do paramagnetic materials not retain magnetization when the external magnetic field is removed?
- Can you provide examples of paramagnetic materials?
Understanding the properties and behavior of paramagnetic materials is important in various fields, including physics, chemistry, and materials science. Mastery of this topic will provide a solid foundation for further studies in magnetism and magnetic materials.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
