[X-Men] Could Magneto use telepathy or mind control by manipulating electrical currents in the brain?
gpt
While potentially he probably could affect the brainwaves through very concentrated magnetic emissions (he IS Master of Magnetism, after all), it's likely be one specific unique feat, non-replicable without certain circumstances.

Magneto can do virtually anything with magnetism, even things magnetism shouldn't be able to do, but those other things usually aren't done casually. 

It's unlikely Magneto would be able to decipher brainwaves enough to count as telepathy or mind control, but he'll probably would be able to exert some crude form of influence if he has the chart on hand.
