Abstract
The magnetic gradient detector has two magnetic field sensors with their magnetic axes arranged parallel to an imaginary line. The sensor electrical outputs are connected with one another such that an electrical signal is created corresponding to the gradient of the magnetic fields present at the respective locations of the sensors. Each sensor has its core suspended on a wire under tension which maintains the parallelism constant. The wires are adjustable to establish initial parallelism or correct for subsequent misalignment that may occur.
