magnetosphere

I am going to call all magnetospheres and heliospheres : magnetosphere.

A hydrogen element as a blackbody object produces a magnetosphere.
An iron magnet as a collection of blackbody objects produces a magnetosphere.
A spinning bowl of oatmeal as a collection of blackbody objects produces a small but detectable magnetosphere.
The earth as a composite of blackbody objects produces a magnetosphere.
The sun as a composite of blackbody object produces a magnetosphere.
The Milky Way Galaxy as a composite of blackbody objects produces a magnetosphere.
Large Galactic Cluster as a composite of blackbody objects produces a magnetosphere.
