[X-men/Marvel] Could Magneto use his control over magnetism to disrupt the electromagnetic fields in a person's brain or heart, thereby killing them instantly? If so, why doesn't he use it all the time?

In one story he did use subtle control over his magnetic field manipulation powers to make someone pass out, but he had to physically touch them. He probably could do more damage if he was inclined to, but if physical proximity is a factor, it'd just be easier to kill them using one of his more common methods from a distance.
