Why does removing Tony Stark's power source weaken him?
My understanding is that the effect of the explosion at the beginning of Iron Man 1 is that Tony Stark has metal shrapnel in his heart and needs an electromagnet to keep it from puncturing his heart.
When Obadiah Stane paralyzes him and tears out his power source, Tony tries to get to an older version, getting weaker and weaker.
How does removing the power source weaken him? It is not powering his body but a device to protect his heart. No power ultimately means a punctured heart but there is no reason to get weaker in the meantime.
Best Answer
Stark has shrapnel surrounding his heart. The arc reactor powers a magnet which keeps the shrapnel from entering his heart and killing him. When the reactor comes out, he starts having the equivalent of a heart attack, which will actually cause rapid weakness, especially given the amount of time that passed before Stane let him out of the paralyzer.

Why did Tony take off his Arc Reactor in endgame?
While Tony no longer needed the arc reactor to keep the shrapnel from entering his heart after Iron Man 3, it's still necessary to power up his suits. Instead of attaching it to his body, he fitted each of his suits with their own arc reactors until Homecoming.What is the weakness of Tony Stark?
We'll start with the most obvious (and most visible) weakness: Tony Stark doesn't really have a strong heart. Well, figuratively, he does, since he spends most of his movie appearances accidentally mentoring Spider-Man and trying to make up for his past mistakes.Why Marvel Wants to Remove Tony Stark
