REMANENCE Meaning and
Definition
-
Remanence refers to the residual magnetic field or magnetization that persists in a material after an external magnetic field or current is removed. It is a property exhibited by certain magnetic materials, such as ferromagnetic substances.
When a magnetic field is applied to a material, it aligns the magnetic domains within it, causing them to point in the same direction. When the external magnetic field is removed, the aligned magnetic domains tend to retain some level of alignment, resulting in a remnant magnetization or remanent magnetism. This phenomenon is known as remanence.
In practical terms, remanence can be observed in the case of permanent magnets. These magnets, made from materials like iron or neodymium, possess a high level of remanent magnetization. Even after being separated from a magnetic field, they still retain their magnetic properties and can attract or repel other magnets.
Remanence is an important concept in the field of magnetic storage, such as hard drives or magnetic tapes utilized for data storage. The ability of a material to maintain remanent magnetization plays a crucial role in these applications, allowing for the recording and retrieval of information.
Overall, remanence describes the residual magnetization retained by a material after the external magnetic field has been removed, making it a fundamental property in understanding and utilizing magnetic materials.
Common Misspellings for REMANENCE
Etymology of REMANENCE
The word "remanence" has its roots in the Latin word "remanentia", which means "remaining". It is derived from the verb "remanere", which combines the prefix "re-" (meaning "again" or "back") and the verb "manere" (meaning "to remain" or "to stay"). In English, "remanence" refers to the state or quality of remaining in or possessing a residual magnetism or magnetic charge.
