SOURCE www.space.com
The sun is on the verge of a magnetic field reversal, which happens roughly every 11 years and marks an important stage in the solar cycle. The reversal could have beneficial effects on Earth, such as shielding it from galactic cosmic rays.

Key Points

  • Sun's magnetic field reversal occurs every 11 years as part of the solar cycle.
  • Reversal marks an important stage in solar activity.
  • The upcoming switch in polarity will have beneficial effects on Earth.
  • The reversal is gradual and not an instantaneous event.

Pros

  • The reversal could shield Earth from galactic cosmic rays.
