The Armor Magnetizer is an item in Going Commando, Tools of Destruction and A Crack in Time, as well as a gadget in Before the Nexus. It increases the magnetic field strength of the worn armor, and allows the user to attract bolts from further away than usual.
The Megacorp Armor Magnetizer was provided to Ratchet in the Megacorp Armory on planet Todano by Stuart Zurgo, a rabid Captain Qwark fanboy. In "Bring Qwark Collectible to Armory Employee", Zurgo demanded Ratchet bring him a Captain Qwark collectible. Ratchet brought him the Qwark statuette (purchased on Aranos from the Plumber in "Purchase Qwark Action Figure").
