magnetisation

Thân thiện

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

Definition

Noun: 1. The physical property of being magnetic: The state or condition of having magnetic qualities, meaning the ability to attract iron or produce a magnetic field. 2. The process that makes a substance magnetic (temporarily or permanently): The act or technique of inducing magnetism in a material. 3. The extent or degree to which something is magnetized: A measure of the intensity or strength of magnetism within an object.

Usage Examples

• Referring to the property:
  • The magnetisation of the lodestone was strong enough to align the compass needle.
  • Scientists studied the rock's natural magnetisation to understand Earth's history.
• Referring to the process:
  • The magnetisation of the steel rod was achieved by stroking it with a permanent magnet.
  • This factory specializes in the magnetisation of components for electric motors.
• Referring to the degree:
  • The magnetisation of the sample increased with the strength of the applied field.
  • They measured the material's magnetisation in units of amperes per meter.

Advanced Usage

• "Saturation magnetisation": The maximum possible magnetisation a material can achieve.
  • Once the iron core reached its saturation magnetisation, applying a stronger field had no further effect.
• "Remanent magnetisation" or "remanence": The magnetisation left in a material after an external magnetic field is removed.
  • The remanent magnetisation of the hard drive platter stores the digital data.

Variants and Related Words

• Magnetize (verb): To make something magnetic.
  • You can magnetize a screwdriver by rubbing it with a magnet.
• Magnetic (adjective): Having the properties of a magnet; capable of being attracted by or producing a magnetic field.
  • Iron is a magnetic material.
• Magnet (noun): An object that produces a magnetic field.
  • She used a magnet to pick up the pins.

Synonyms

• Magnetic polarization (technical, for the internal alignment)
• Magnetic induction (often refers to the process or the resulting internal field)

Related Phrases and Technical Terms

• Magnetisation curve: A graph showing how a material's magnetisation responds to an applied magnetic field.
  • The magnetisation curve revealed the ferromagnetic properties of the alloy.
• Direction of magnetisation: The orientation of the magnetic field within a material.
  • In a bar magnet, the direction of magnetisation runs from the south to the north pole inside the material.
