Several are: 1. A magnetic compass will always point to the North Magnetic Pole. 2. We have the Northern (and Southern) Lights. 3. We are shielded from deadly radiation emitted from the Sun.
Charged particles emitted from the sun get caught in the "magnetic wells" at the earth magnetic poles caused the the shape of the earth's magnetic field, exciting the air molecules there, and causing them to emit light.
beta, aka an electron.
This is a gamma ray. It is very high frequency electromagnetic radiation.

The Magnetosphere attracts charged particles emitted form the sun.

Most of the radiation emitted by hydrogen flames is in the ultraviolet spectrum, which is invisible to humans. This usually makes the flames colorless, but they sometimes have a very faint blue or purple tint.
Earth has its own magnetic field which is emitted from iron core. This protects us from harmful rays. But it does not have an electric field
It's the interaction between the Earth's magnetic field and charged particles emitted from the Sun (the solar 'wind').
This is a gamma ray. It is very high frequency electromagnetic radiation.
