Measurement of Sudden Displacements in Superconducting Coils using Search-coils
Search-coils, which can detect magnetic field variations, have been applied to the measurement of superconducting coil displacements. The advantage of the search-coil is that it can measure displacements which occur in an arbitrary section of a superconducting coil without making contact with a winding.

Inductive localization accuracy of a passive 3-D coil in an Industry 4.0 environment [PDF]
In this paper a localization system of a passive 3-D coil is proposed and signal uncertainties due to the 3-D coil's arbitrary orientation are analyzed. The 3-D coil is excited by an alternating primary magnetic field.

Routine phasing of coiled-coil protein crystal structures with AMPLE
Coiled-coil protein folds are among the most abundant in nature. These folds consist of long wound α-helices and are architecturally simple, but paradoxically their crystallographic structures are notoriously difficult to solve with molecular-replacement

The magnetic analog with spiral search coils [PDF]
The teaching of field theory is often enriched by citing analogies among the various potential fields: heat flow fields, fluid flow fields, current flow fields, electric fields, magnetic fields, etc. Thus, the magnetic analog is old in theory. However, it appears that it has not heretofore been developed into a fully useful device.
