Curie Point (noun)

Definition: The Curie point is the temperature at which a material that is normally magnetic (like iron) loses its magnetism. Above this temperature, the material becomes "paramagnetic," meaning it can still be attracted to a magnet, but it does not retain any magnetism when the external magnetic field is removed.

Usage Instructions:

• The term "Curie point" is typically used in scientific contexts, especially in physics and materials science.
• It is often discussed when talking about the properties of metals and their behaviors under different temperatures.

Example:

• "Iron has a Curie point of about 770 degrees Celsius. Above this temperature, it no longer behaves like a magnet."

Advanced Usage:

• In advanced studies, you might see the Curie point referred to in discussions about phase transitions in materials or in the study of magnetic properties of alloys.

Word Variants:

• Curie Temperature: This is another way to say Curie point; both terms are often used interchangeably.

Different Meanings:

• The term "Curie" is also associated with Marie Curie, a famous scientist known for her work in radioactivity. In this context, it refers to a unit of radioactivity but is unrelated to the Curie point.

Synonyms:

• There are no direct synonyms for "Curie point" in the scientific context, but you might see it referred to as "Curie temperature" in literature.

Idioms and Phrasal Verbs:

• There are no common idioms or phrasal verbs directly related to "Curie point," as it is a technical term.

Summary:

The Curie point is an important concept in understanding the behavior of magnetic materials when exposed to high temperatures.
