magnetopause

magnetopause

1 9.9
The boundary around a planet where its magnetic field meets the solar wind
  • noun
  • /ˈmæɡnɪtəˌpɔs/
  • Specialized
: magnetopausa
  • At the magnetopause, the pressure from the solar wind balances the magnetic force of the planet.

Examples

  • The satellite passed through the magnetopause, marking the transition between the solar wind and the planet's magnetic field.

  • Furthermore, reconnection events near the magnetopause are dynamically driven by the impact of the magnetic field frozen into the solar wind ramming into the magnetosphere.

    Academic text (2006)

  • Scientists study the magnetopause to understand how solar wind interacts with planetary atmospheres.

Morphology

magnetopause = magnet + pause (semi-transparent) = magnet + pause

Composed of the clear elements 'magnet' and 'pause', but the technical specialised meaning ('boundary where a planet's magnetic field balances the solar wind') is domain-specific and not obvious to general learners.

Etymology

Magnetopause starts with magnet (a thing that pulls iron) and ends with pause from a root meaning 'stop'. It names the edge where a planet's magnetic field 'stops' or balances the solar wind, so it is the boundary between space controlled by the magnet and space filled by the wind.
