I was thinking one day and came up with a theory after reading about how scientists were studying anti-matter by using electromagnetic fields to separate matter from the anti-matter they made. It got me thinking, would it be possible to use very powerful electromagnetic fields to break down the molecular structure of objects or build things in this way?
Is this molecular reconstruction with electromagnetic fields theoretically possible? That is, is it theoretically possible to use electromagnetic fields generated by a machine to separate the parts of a molecule thereby deconstructing an object on the molecular/atomic level?
I'm not asking about taking apart atoms, but rather taking actual molecules apart. If it's possible to break molecules apart with electromagnetic fields, is it also possible to use a similar process to assemble them?
(I'm writing an essay about this, but I'm having a hard time finding information that can help me with this.)
