A proposal for detection of absolute rotation using superconductors and large voltages

We describe designs for practical detectors of absolute rotation, which rely on the creation magnetic fields by charged objects that are rotating with respect to an inertial frame. Our designs, motivated original suggestion R.M. Brady, utilise properties superconductors, both shield and confine fields, also as basis a SQUID detector produced. show commercially available SQUIDs, our can have sufficient sensitivity signal-to-noise ratio measure sidereal rate rotation Earth. consider three different designs: two these be configured provide confirmation form Maxwell's equations take in make direct experimental test whether low-frequency electromagnetic energy experience same rest-frame matter.
