actually I've heard, that if you just learn electrokinesis and develop it more towards electro-static and electro-magnetic fields, then you'll develop magnokinesis
not really because geo is more earths natrural substances, the only metals that are in a metal form when found are silver and gold all other metals are either compounds or extracted from rocks. ( i think )
well, you could learn telekinesis to manipulate metal, but if you focused mainly on the electromagnetic part of electrokinesis, you would get a stronger result and therefore would be able to manipulate more metal at once and heavier and denser metals as well
