Answer
Harmful space particles would reach Earth and endanger life.

Explanation

  • The magnetic field normally pushes away harmful particles.
  • Without it, cosmic rays and solar wind would hit the Earth.
  • They could damage the atmosphere and reduce the ozone layer.
  • So more harmful UV rays would reach us and harm living cells.
No magnetic shield means harmful particles threaten life.
