Basic principle of magnetic fields at work. (Score 1)

This its a basic principle that has been around since the 1800's. Flemming's left hadn't rule is at work. "When current flows through a conducting wire, and an external magnetic field is applied across that flow, the conducting wire experiences a force perpendicular both to that field and to the direction of the current flow (i.e they are mutually perpendicular) ." Great testing by the researchers. Here is a link to an explanation of Flemming's left hand rule: https://en.wikipedia.org/wiki/... . I'm actually surprised this wasn't found earlier.
