Definition

1. Noun (Physics):
   • The amount of magnetic flux in a unit area perpendicular to the direction of magnetic flow: This is a quantitative measure of the strength of a magnetic field, also commonly called magnetic flux density.
   • The process that makes a substance magnetic (temporarily or permanently): This refers to the phenomenon where a material becomes magnetized when placed within an external magnetic field.

Usage Examples

• Noun (Flux Density):

  • The device measures the magnetic induction inside the coil.
  • A high magnetic induction is required for the experiment to work.

• Noun (Process of Magnetization):

  • The magnetic induction of the iron rod was achieved by placing it near a strong magnet.
  • This material is known for its ease of magnetic induction.

Advanced Usage

• "Magnetic induction" is a core concept in electromagnetism. The first meaning (flux density) is a vector quantity, symbolized by B, and its SI unit is the tesla (T).
• In engineering contexts, magnetic induction often specifically refers to the process of inducing an electromotive force (EMF) in a conductor by changing the magnetic field around it, which is the principle behind electric generators and transformers.

Variants and Related Words

• Induction (n): The general process of causing something to happen without direct contact. In electromagnetism, it often refers to electromagnetic induction.
• Magnetization (n): The process or result of making a material magnetic, closely related to the second meaning of magnetic induction.
• Magnetic flux density (n): A direct synonym for the first meaning of magnetic induction.
• Electromagnetic induction (n): The production of an electromotive force across an electrical conductor in a changing magnetic field.

Synonyms

• Magnetic flux density (for the first meaning).
• Magnetization (for the second meaning, specifically the result).
• Magnetic B-field (technical synonym for the first meaning).

Related Phrases

• Law of magnetic induction: Often refers to Faraday's law of electromagnetic induction, which quantifies how a changing magnetic field induces an electric voltage.
  • Faraday's law of magnetic induction is fundamental to electrical power generation.
• Induced magnetism: The magnetism created in a material due to magnetic induction.
  • The induced magnetism was temporary, fading after the external field was removed.
