EM Drive thrust due to poorly shielded cables

[llkiwi2006]

From the conference paper:

Special attention is given to the investigation and identification of error sources that cause false thrust signals. Our results show that the magnetic interaction from not sufficiently shielded cables or thrusters are a major factor that needs to be taken into account for proper μN thrust measurements for these type of devices.

However, we found that e.g. magnetic interaction from twisted-pair cables and amplifiers with the Earth’s magnetic field can be a significant error source for EMDrives.

Working with large currents and tiny forces, but don't have proper shielding

I called it when they first announced such inconsistent and puny results.  Victory goes to Lorentz.

experiment needs to be repeated with greater shielding, to verify
