This chapter describes induction magnetometers with air-core coils for weak magnetic fields
detection. In order to explain the historical background, the introduction provides the useful …

A magnetometer with a coil is capable to use two methods [1]. The first method is based on
Faraday's law that the induced voltage across the coil is proportional to the derivative of the …

Proposal of coil structure for air-core induction magnetometer is presented. The key point is
the lamination factor which refers to the ratio of winding number compared with an ideal …

This research enhances the haptics display that usually functioned as a dynamic Braille
Letter, with an ability to vary the dynamic pins' height. These height variations can be utilized …

The wireless transfer of electricity has gained vast importance in recent years. Many
attempts had been done in this regard. The information generated is quite scattered and …

Stable operating conditions for a high-sensitivity induction gradiometer are studied
experimentally. In order to reduce electrical interferences in our developed induction …
