Which layer acts like a giant magnet and what does it attract in the atmosphere?

The layer that acts like a giant magnet is the Earth's magnetosphere. It attracts charged particles from the solar wind, primarily electrons and protons. This interaction protects the Earth from harmful solar radiation and cosmic rays, while also contributing to phenomena like the auroras. The magnetosphere is crucial for maintaining the planet's habitability by shielding the atmosphere from erosion by solar winds.
