Abstract
Stable operating conditions for a high-sensitivity induction gradiometer are studied experimentally. In order to reduce electrical interferences in our developed induction gradiometer, we construct a Faraday cage. It consists of copper mesh and wood, and is 2.0 mtimes1.8 mtimes1.8 m in size. Experimental results show that the inside of the cage can provide a quiet electrical environment where the electrical interference is suppressed. Choosing a suitable grounding point for the electronics, undesirable signals in the sensor output are cleaned. Observation of a weak magnetic field is also demonstrated.
