Since Michael Faraday's first demonstration of the electric generator there has been a controversy about the relationship between the electric and magnetic fields that are measured by a static observer and those measured by an observer on a roundabout. The problem has been solved using standard relativity theory but the predictions have not been fully explored experimentally. One consequence of the theory is that a magnetic field is produced by the rotation of an electrostatically charged ring and, crucially, that the magnitude of this field is proportional to the rotation rate relative to the fixed stars. This coupling of local physics to the rest frame of the Universe is analogous to that found in Newtonian mechanics.We intend to construct a device that is based on this fascinating principle and use it to detect the rotation rate of the Earth from the confines of a terrestrial laboratory. This will be the first demonstration of an electromagnetic gyroscope. The device will be based on existing laboratory equipment and consumables available at the INFN Legnaro National Laboratory. The travel grant will be used to fund accommodation in Padua, Italy, for 6 months.

自从迈克尔·法拉第第一次演示发电机以来，关于静电观测者和环岛观测者测量的电场和磁场之间的关系一直存在争议。这个问题已经用标准相对论解决了，但这些预测还没有在实验中得到充分的探索。该理论的一个结论是，磁场是由一个带静电电荷的环的旋转产生的，至关重要的是，这个磁场的大小与相对于固定恒星的旋转速率成正比。这种局部物理与宇宙其余框架的耦合类似于牛顿力学中的耦合。我们打算建造一个基于这一迷人原理的装置，并利用它在地面实验室的范围内检测地球的自转速度。这将是电磁陀螺仪的首次演示。该设备将基于INFN Legnaro国家实验室现有的实验室设备和消耗品。旅行补助金将用于支付在意大利帕多瓦6个月的住宿费用。
