Subject: When electricity is generated, where do the electrons originate?

We understand that electricity is the movement of electrons across a 
conductor.  We also understand that electricity is generated from a magnetic 
field.  But if electriciy is electrons in motion, where do they originate?  
When electricity is generated does this not cause matter to be stripped of its 
elctrons?  If so, then isnt this matter now changed?  I am the CEO of an energy 
company with minor science background and work with engineers, so far no one 
has answered this question.  THANKS Paul Mendell, Mendell Energy
