- 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,
