The required field was imposed with internal magnets once it was discovered that the terrestrial field was responsible for the rotation of the filament.

But this has never been done in reality. It’s all theoretical at this point. Eric thinks that it will work. I think it will work. How strong of a magnetic field produces the best result? Can the same result be obtained without the coil, merely by changing the orientation of the electrode? How do we know, if we don’t know what the optimal field strength is?
