Reply to comment by team-tree-syndicate in How much does the liquid magma of the Earth affect it's surface temperature? by tripperfunster

That's actually an interesting question, About how magnetic fields really traps "anything". Tonight I will be going down a rabbit hole.

After some thinking, my best guess would be the prevention of radiation from the sun. Without a magnetosphere, cosmic wind would "blow" away the atmosphere.

Just to bei more specific, the radiation from the sun which get's blocked/deflected by earths magnetic field are charged particles (e.g. alpha/beta-radiation).

The radiation which "heats" earth ist gamma-radiation in form of photons. A good portion of those photons get reflected by clouds and ice (due to the reflectiveness of white surfaces), another part afterwards get's radiated as infrared-radiation. The Difference between the incoming and (reflected + radiated) photons are the energy earth get's from the sun.
