If his powers were only magnetism he wouldn't be an omega class mutant (the highest threat level of a mutant), the more you know:
* Magnetic Force-Fields: Magneto usually protects himself with a personal force field that he can quickly expand to protect large areas. His force field has withstood the effects of multiple nuclear weapons, volcanic eruptions, the depths of space and attacks from multiple Avengers or X-Men, including Phoenix, Thor, and even Galactus.
* Magnetic Flight: Magneto is also capable of sustaining flight for very long distances and at varying speeds. He apparently has several means by which he achieves flight, one of which is by gliding along the planet's natural magnetic lines of force, another by simply creating a repulsive force between himself and the planet, propelling himself thus. By using his magnetic powers, Magneto can virtually travel at trans-light speeds; however, in order to travel in space, Magneto also requires his force field to breathe.
* Matter Manipulation: Magneto is able to manipulate matter even to the subatomic level for a number of purposes[15]. This might explain why, his not limited to objects with metallic properties and is able to manipulate objects with non metallic properties like wood, stone, plastics etc. to such a degree[16].
* Electromagnetic Sight: By concentrating, Magneto can perceive the world around himself as patterns of magnetic and electrical energy. He can perceive the natural magnetic auras surrounding living beings.
* Metallic Bonding: Magneto has recently presented the power to atomically bond metallic substances to any designated surface material. This newly developed technique allows Magneto to blend metallic alloys with the earth, water, and air (HoM).
* Organic Iron Manipulation: Magneto can control the traces of iron within organic matter, which allows him to have full control over an opponent's body. He can manipulate the iron-enriched blood-flow to one's brain to induce aneurysms or unconsciousness, alter thoughts and perceptions, or blank a person's mind completely. He can even remove ferrous compounds from the bloodstream entirely through a person's skin. Magneto has used his magnetic abilities to extract the Adamantium bonded to Wolverine's biomolecular skeletal structure.
* Geomagnetic Link: Magnus is tied very closely to Earth's EM Field. As is it effected, so is he. He knows instinctively all that happens to it, and with this link, is granted an odd sort of immortality. Earth lends him strength by it's simple existence. He draws on it all unconsciously.
* Superhuman Strength: Under normal conditions, Magneto possesses the physical strength of a well conditioned athlete. However, he can channel vast amounts of magnetic energy through his body for the purpose of granting himself vast superhuman strength which limits are unknown. Whatever those limits might be, he is ultimately able to lift far in excess of 100 tons with ease.
* Superhuman Stamina: As a result of increasing his strength, he dramatically increases the overall efficiency of his musculature. While magnetically enhanced, his muscles produce considerably less fatigue toxins during physical activity than the musculature of a normal human. Magneto can exert himself physically for up to at least a few days before the build up of fatigue toxins in his blood starts to impair him.
* Superhuman Durability: Under normal conditions, Magneto possesses the physical durability of a well conditioned athlete. However, he can channel vast amounts of magnetic energy through his body for the purpose of granting himself vast superhuman durability, to the point he can shrug off punches to the face from super humans such as Namor and Colossus while weakened and remain unharmed[17].
* Superhuman Reflexes: He naturally possesses enhanced reflexes. He can further enhance this reflexes with magnetic energy, to the point he can pluck out of the air with his hand, superhumans as swift and fast as the likes of Northstar with ease.
* Superhuman Speed
Electromagnetic Spectrum Manipulation: Although Magneto's primary power is magnetism, he has some ability to project or manipulate any form of energy that is related to the electromagnetic spectrum. He can fire and absorb bolts of electricity and magnetic force, reverse lasers and other forms of radiation or energy, create enough intense heat as infrared radiation to level a city, manipulate gravity, and become invisible by deflecting visible light around his body. Infrared radiation is part of the electromagnetic spectrum, which also includes visible light, radio waves, ultraviolet light, gamma rays and x-rays -- Magneto can project any of these. Magneto has demonstrated the capacity to produce a wormhole, and to safely teleport himself and others by means of the wormhole.
Astral Projection (Possibly Formerly): Magneto has occasionally been said to be able to manifest an astral projection of himself[18]. However, like all formerly attributed psychic powers, this has been retconned out of existence at least once [8], and hasn't been used by Magneto since the "Silver Age" (chronologically speaking), possibly implying any such abilities were lost during his regression to childhood by Mutant Alpha[citation needed].
Telepathic Resistance: Magneto has trained himself extensively for fighting telepaths, and is resistant to telepathic attack. This training is similar to that given to the X-Men and New Mutants by Professor X, although the effects are further augmented with the aid of his helmet (see below). Additionally, Magneto is possessed of a strong will, which also aids him in resisting telepathic assaults.
