Ratio of Charge to Mass (e/m) for the Electron
... Now turn the magnetic field back on, and bring one end of a bar magnet as close as you can to the electrons' path and observe the spiral path which the electrons now follow. Can you explain why the presence of the extra field distorts the electron's path? How will the Earth's field affect the motion ...

... magnetic field at a point below the wire is from north to south. The direction of magnetic field at a point directly above the wire is from south to north Q. Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. Apply the right-hand rule t ...
