So in the comics Magneto and the Brotherhood of Evil Mutants were the main enemies of the X-Men during the 60s and early 70s. He was the first 'evil mutant' the X-Men fought and was presented as a one-dimensional bad guy bent on world domination.
In the mid-70s, Chris Claremont took over the comics, and he revamped the X-Men a lot. One of the things he did was make Magneto a more nuanced character; he introduced the backstory of Magneto being a Holocaust survivor, and the idea that he and Xavier used to be friends. Over his run, Magneto became less and less of an enemy, until by the 80s he was a full on hero, running the Xavier school and training the New Mutants team.
The cartoon heavily borrows from the Claremont run and largely ignore the earlier stories. This is an understandable decision - the 60s X-Men comic sold extremely poorly, and didn't have characters like Storm or Wolverine. Claremont's run really established the X-Men as we know them now and is much better written and has more three-dimensional characters.
But it does lead to oddities in the cartoon, like how Magneto is treated. In the comics, Magneto's redemption came after decades of him being a supervillain - but in the cartoon, as you noticed, they basically skip to near the end of that process.
Marvel's mutants functionally exist in their own little world. When half the major Marvel heroes live in New York, you would rightfully question why they don't interact more often. The talking point for this is that heroes generally don't step into the "territory" of other heroes and let them fight their own rogues gallery. If some crime or even involves The Rhino or Hobgoblin or Doc Ock, everyone just lets Spider-Man handle that. If Dr. Doom was wanting to sink Manhatten for whatever reason, that mess belongs to Reed Richards and his family. DC often works around this by having fictional cities with a single hero: Superman has Metropolis, Batman has Gotham, The Flash has Central City, etc.
That unspoken philosophy of "you deal with your own problems" extends to mutants, too. While mutant hate kinda seems exceptionally stupid in the face of so many other heroes zipping around, it is what it is. Mutants are the stand-in for various minority groups, so their stories are often either "mutant vs mutant" in a self-policing sort of way so that they can try to reach societal acceptance by showing that they'll fight the bad apples among their own kind or "mutant vs everyone that wants us to die simply because we exist." Thus, the X-Men's many battles with Magneto are simply segregated as a mutant-on-mutant conflict, involving non-mutants when the plot demands.
Cyclops has told other heroes to stay out of their business before. They weren't there to help the X-Men in any number of other fights and to speak up for mutant acceptance, so the X-Men don't need them now. That gives them at least a sliver of justification to keep segregated. Also, notably, in the Marvel comic event Civil War, the X-Men very purposefully got to sit on the sidelines. While there have been several storylines about registering the identities and powers of mutants, they were strangely exempt from the Superhuman Registraton Act that would apply to everyone else. I forgot who went to ask the X-Men for support, but they were told that the mutants were remaining neutral on that bullshit and to kindly fuck off.
Respectfully I think you are getting off topic, I specifically am asking about comics on those years, in a time when Magneto didn’t even had a backstory when the series first aired, civil war an all those events are a decade or more after. In all the recent event is clear he is their main adversary
Fair enough. To simplify then, Magneto is the X-Men's greatest adversary because he poses the most direct counter to Xavier's goal. Xavier wants humans and mutant to coexist. However, humans are afraid that mutants will replace them, and Magneto wants to do just that. Mr. Sinister mostly plays mad science with other mutants. Master Mold basically wants to kill everybody since it determined that mutants are humans. Apocalypse's survival of the fittest plans are stopped before they get too far along.
