current were flowing in the area between A and B, it's either going

You know that there can be voltage without current, right?


They come in both types, as a current sensor or as a voltage sensor,
or some of them have dual mode. It is a handy device because it is a
noncontact measurement.
I think the original poster was saying current when he actually meant
voltage.
