Paramagnetic

Paramagnetism is a property of certain materials that are attracted by an external magnetic field. This attraction is the result of unpaired electrons in the atoms of the material. When exposed to a magnetic field, these unpaired electrons align their magnetic moments in the direction of the external field, causing the material to be attracted to the magnet.

Characteristics of Paramagnetic Materials

• Contain unpaired electrons
• Attracted by an external magnetic field
• Do not retain magnetization when the external magnetic field is removed
• Weaker response to the magnetic field compared to ferromagnetic materials

Examples of Paramagnetic Materials

Some common examples of paramagnetic materials include:

• Oxygen
• Aluminum
• Platinum
• Titanium
• Manganese

Study Guide

Here are some key points to remember about paramagnetic materials:

1. Paramagnetism is a property exhibited by certain materials with unpaired electrons.
2. These materials are attracted to an external magnetic field due to the alignment of their unpaired electrons.
3. Paramagnetic materials do not retain their magnetization when the external magnetic field is removed.
4. They exhibit a weaker response to the magnetic field compared to ferromagnetic materials.
5. Examples of paramagnetic materials include oxygen, aluminum, platinum, titanium, and manganese.
