997 - How does the Earth's magnetic field protect us from harmful radiation?

The Earth's magnetic field acts like a shield to protect us from harm. Here's how:

1. Space has radiation: There are tiny particles of energy called radiation moving through space. Some of this radiation can be hurtful to humans and other living things.
2. Magnetic field blocks radiation: The Earth's magnetic field is like a big "Force Field". It blocks and deflects most of the radiation coming from space.
3. Radiation is redirected: When radiation hits the magnetic field, it gets redirected away from the Earth. This means the radiation doesn't reach us on the ground.
4. We're safe on the ground: Because of the magnetic field, we're protected from the radiation. It helps keep us safe and healthy.

It's like having a shield around the whole Earth that keeps us safe from the harm that radiation can cause.
