This question already has an answer here:

How do you positively charge something consistently? By what mechanism could this be achieved?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Simple. Bring a negatively charged object nearer to your object so that electrostatic induction could be possible. BTW, Hi Pmeister, Welcome to Physics.SE. I think I've seen a similar question ;-) – Waffle's Crazy Peanut Mar 11 '13 at 15:20
Thanks Crazy Buddy. I checked out the other post you suggested. I couldn't quite figure out how I could physically use a power source to continuously positively charge an object. I am a novice so you may have to really dumb it down for me! – user807261 Mar 11 '13 at 15:45
Well, your post doesn't say a word about "continuously" or "constantly" - which is the necessary keyword. Does that "consistent" actually means "continuous" here ?? (If so, pardon me for that) :D – Waffle's Crazy Peanut Mar 11 '13 at 15:48
Sorry for the confusion. Yeah thats what I was attempting to say. I am trying to basically use a power source to consistently induce a positive charge in an object, but Im not sure how to go about setting that up physically. – user807261 Mar 11 '13 at 15:52
I think I still can't catch up. Induction is good even if there's a constant power source. – Waffle's Crazy Peanut Mar 11 '13 at 15:55

Take a simple capacitor across a (DC) battery: one plate will be positive the other negative. There will be a transient current until the plates are saturated.
