Claim 16:
17. A method of detecting a metallic chip in engine fluid of an engine using an electromagnetic chip detector, the method comprising:
supplying an electric current to a circuit extending between a first node and a second node to magnetize both a first electrically conductive terminal and a second electrically conductive terminal spaced apart from each other to define a chip-receiving gap therebetween; and
detecting a change in resistance across the first node and the second node, the change in resistance being indicative of a capture of the metallic chip by the electromagnetic chip detector, the metallic chip electrically connecting the first electrically conductive terminal to the second electrically conductive terminal, the first electrically conductive terminal being electrically connected to the first node, and the second electrically conductive terminal being electrically connected to the second node.
