论文摘要
我们描述了绝对旋转的实际检测器的设计，这些探测器依赖于通过相对于惯性框架旋转的带电物体创建磁场的设计。我们的设计是由R.M.的原始建议的动机布雷迪（Brady）利用超导体的特性来屏蔽和限制磁场，也是产生的磁场检测器的基础。我们表明，使用市售的鱿鱼，我们的设计可以具有足够的灵敏度和信噪比，以测量地球旋转速率。我们考虑三种不同的设计：其中两个也可以配置为确认麦克斯韦方程在旋转框架中采取的形式。我们还可以直接进行实验测试，以了解低频电磁能量是否与物质相同的惯性休息框架。
We describe designs for practical detectors of absolute rotation, which rely on the creation of magnetic fields by charged objects that are rotating with respect to an inertial frame. Our designs, motivated by an original suggestion by R.M. Brady, utilise the properties of superconductors, both to shield and confine the magnetic fields, and also as the basis of a SQUID detector of the fields produced. We show that with commercially available SQUIDs, our designs can have sufficient sensitivity and signal-to-noise ratio to measure the sidereal rate of rotation of the Earth. We consider three different designs: two of these can also be configured to provide a confirmation of the form that Maxwell's equations take in a rotating frame. We can also make a direct experimental test of whether low-frequency electromagnetic energy experience the same inertial rest-frame as matter.
