Abstract
Systems and methods are described for improving foreign object detection for ferromagnetic wire-like objects. In particular, aspects include increasing FOD sensitivity using at least one inductive sense loop in response to detecting a change in resistance that is substantially equal to the change in reactance of a sense coil. By increasing the FOD sensitivity, objects such as ferromagnetic wire-like objects can be detected that are potentially hazardous objects. Detecting these potentially hazardous objects that were previously undetectable can reduce the chances of damage to surrounding materials or harm to humans.
