A bar of iron shows strong magnetization after being placed near a magnet.

Definition

1. Noun:
   • The physical property of being magnetic: The state or quality of having magnetic force or attraction.
   • The process that makes a substance magnetic (temporarily or permanently): The act or technique of inducing magnetic properties in a material.
   • The extent or degree to which something is magnetized: A measure of the strength of the magnetic moment within a material.

Usage Examples

• Noun:
  • The magnetization of the iron bar was evident when it attracted nearby paperclips. (The property of being magnetic in the iron bar was clear.)
  • The magnetization process involves aligning the material's internal domains. (The process of making it magnetic involves this alignment.)
  • Scientists measured the rock's magnetization to study the Earth's ancient magnetic field. (They measured the degree to which the rock was magnetized.)

Advanced Usage

• "Saturation magnetization": The maximum possible magnetization a material can achieve.
  • Once it reached saturation magnetization, applying a stronger external field produced no increase.
• "Remanent magnetization": The magnetization left in a material after an external magnetic field is removed.
  • The remanent magnetization of the volcanic rock provided a record of the field's direction when it cooled.

Variants and Related Words

• Magnetize (verb): To make magnetic or to attract strongly.
  • You can magnetize a steel needle by stroking it with a magnet.
• Magnetic (adjective): Having the properties of a magnet; capable of being attracted by or acquiring the properties of a magnet.
  • The magnetic strip on the card stores data.
• Demagnetization (noun): The process of removing magnetic properties.
  • Demagnetization is necessary before repairing some electronic devices.

Synonyms

• Magnetic polarization: (Physics) Often used interchangeably in technical contexts to describe the alignment of magnetic moments.
• Magnetic induction: The process of magnetizing a material by placing it in a magnetic field.

Related Phrases

• Magnetization curve: A graph showing how a material's magnetization changes with an applied magnetic field.
  • The magnetization curve revealed the material's ferromagnetic properties.
• Magnetization direction: The orientation of the magnetic field within a material.
  • Data on a hard drive is stored by flipping the magnetization direction in tiny regions.
