釋義

A maxwell is a scientific unit for measuring magnetic flux in the CGS system. One maxwell equals the magnetic force passing through a one-square-centimeter surface held at a right angle to a uniform field with a strength of one gauss.

例句

In the physics report, one maxwell was defined as the magnetic flux crossing a surface of one square centimeter.

definition context: one maxwell equals…

Naoko calculated that the small electromagnet produced a magnetic flux of roughly 250 maxwells.

collocation: flux of [number] maxwells

同義詞
  • Mx

    Standard abbreviation; used in equations and tables instead of writing 'maxwell'

  • line of magnetic flux

    Historical equivalent; one maxwell was originally defined as one line of force per square centimetre

  • CGS unit of magnetic flux

    Descriptive label identifying its place in the measurement system

文法句型

[number] maxwell(s)

measured in maxwells

用法筆記

Rare outside of physics and engineering contexts. In the modern SI system the standard unit of magnetic flux is the weber (Wb); one maxwell equals 10⁻⁸ weber. The abbreviation is Mx.

常見錯誤

❌The magnetic field strength was 100 maxwells.
✅The magnetic field strength was 100 gauss.
💡Maxwells measure magnetic flux, not field strength.
❌One maxwell equals one weber.
✅One maxwell equals 10⁻⁸ weber.
💡The maxwell is much smaller than the weber (1 Wb = 10⁸ Mx).
❌The magnet produced 50 maxwells of field intensity.
✅The magnet produced 50 maxwells of magnetic flux.
💡Intensity and flux are different physical quantities.
