magnetic flux

A bar magnet sits on a table with iron filings showing its magnetic flux.

Definition
  1. Noun:
    • The lines of force surrounding a permanent magnet or a moving charged particle: This refers to the pattern of invisible magnetic field lines that emanate from a magnetic source, depicting the direction and shape of its magnetic influence.
    • A measure of the strength of a magnetic field over a given area: This is a quantitative scalar physical quantity, representing the total magnetic field passing through a specified surface area.
Usage Examples
  • Noun:
    • The iron filings revealed the magnetic flux pattern around the bar magnet.
    • The engineer calculated the magnetic flux through the coil to determine the induced voltage.
Advanced Usage
  • "Rate of change of magnetic flux": A key concept in electromagnetism, particularly in Faraday's Law of Induction, which states that a changing magnetic flux induces an electromotive force (EMF).
    • The induced current is proportional to the rate of change of magnetic flux.
Variants and Related Words
  • Magnetic flux density (B): Also called the magnetic field strength, it is the amount of magnetic flux per unit area. It is a vector quantity measured in teslas (T).
    • The magnetic flux density inside the solenoid was very high.
  • Flux linkage: The total magnetic flux linked with a coil, which is the product of the number of turns and the flux through each turn.
    • Increasing the number of turns increases the flux linkage.
Synonyms
  • Magnetic field lines (for the conceptual pattern).
  • Magnetic field flux.
Related Phrases
  • Magnetic flux conservation: In a closed surface, the net magnetic flux is always zero, a principle derived from Gauss's law for magnetism.
    • The law of magnetic flux conservation implies there are no magnetic monopoles.
  • To cut magnetic flux: Describes the motion of a conductor relative to magnetic field lines, which can induce a current.
    • The moving wire cuts the magnetic flux, generating electricity.
