I serierna är det kanske inte hans hjälm som skyddar honom. Han är ofta visad som egen psykiska förmåga. Wikipedia har detta att säga om det:
(a) technology wired into his helmet (the explanation given in the X-Men film series and several comic plotlines), (b) some physical aspect of his electromagnetic powers that can interfere with telepathy (he once used the Earth's magnetic field to dampen the powers of all telepaths within his reach), (c) latent telepathic powers of his own or (d) sheer force of will (cf. X-Men Vol. 2 #2). The theme of latent telepathic powers has been explored in a number of stories, among them the Secret Wars limited series. In some of his earliest appearances, Magneto was depicted as capable of engaging in astral projection. He has used Cerebro to locate mutants at great distances while leading the New Mutants.[volume & issue needed] He has also, on rare occasions, been shown reading other's dreams, issuing telepathic commands, and probing the minds of others.[114] He has demonstrated the ability to shield his mind, while in intense meditation, so completely that even Emma Frost was not able to read his thoughts, despite being directly in front of him and actively attempting to do so.
