Why is Magnetism important to study when looking at the Universe and Stars?

magnetism is very important because we use it to create electrical energy. the Milky Way's magnetism is produced by electrical currents. But while the Earth has a molten core to carry these currents, our galaxy's magnetism is powered by uncounted numbers of electrons, slowly drifting in formation through space. this creates a very powerful magnet.

*sigh*

Because it holds the universe together.

Explanation: While there are many factors that went into the creation of the universe, its important to study magnetism and learn its role in shaping our universe. Planets are formed by magnetism, when a rock(s) breaks off and is floating towards a larger object it will often join it, the bigger the object the more magnetism it has, so has rocks and materials gather together, magnetism always has an effect in it. Not to mention our solar system is held together with magnetism, the planet's orbit relies on magnetism to keep them in line, or else there would most definitely be collisions.

The stars are made up of particles as well as other materials joined and held together by magnetism.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
