Flares etc: why do they only exist on stars?

[Sariaht]

Why can't the earth's magnetic field go bazooka!

It's made of iron and it's got poles...

[Nenad]

arent flares a product of extrememly high magnetic fields, and plasma reactions. Also, our magnetosphere is too bisy protectiong us from the suns flares in order to have its own.

[Sariaht]

Perhaps these things that errupts after flares are caused by fusion within a rotating body, causing a flow that changes it's magnetic field, why planets can't have them unless it's core is made of pure uranium or something.

No, I meant the corona: Perhaps the corona is caused by fusion within a rotating body, causing a flow that changes it's magnetic field, why planets can't have them unless it's core is made of pure uranium or something.

What would uranium have to do with anything. The sun is made up of a lot of hydrogen. Wery little uranium.
