The title says it all: "How does a clamp-on ammeter work?" I'm thinking about one of the gadgets used to measure the current in an automobile charging circuit, for instance. It has a pair of thick "jaws" that encircle the lead in question, and a meter that reads out the current passing through the encircled region, without intrusively breaking or touching the wire. Does it sense the B field? If so, how? Thanks, B. Allen Please reply to ballen@dirac.phys.uwm.edu
