When the specimen is inserted or moved through the search coil cross section, the induced emf can be detected and measured and expressed by the following relationship:

Alternatively, the EMF can be directly measured by placing a search coil in the SRM phase (Fig.
Ziffer et al classified DEP into three subgroups, using scleral search coil technique for evaluating saccadic velocities into groups of IR restriction, complete or incomplete SR paralysis and supranuclear palsy (6).
Search coil sensors give a voltage signal proportional to the flux density of the field passing through the sensing element.
The time varying signal of the search coil output would be processed through a combination of signal conditioner, filter and an amplifier.
Plus, the M-97 offers auto-tune circuitry and a waterproof search coil. Other features include ground effect rejection VLF that eliminates annoying or false signals from wet ground foliage, pavement or mineralized ground; and a compact size for convenient storage.
Now, with the introduction of their Metalarm 3500 metal detection system and its associated PL-type plate search coil, tramp metal contained in products being transported can be detected without the need for extended feed trays or metal-free sections, say Eriez of Bedwas House Industrial Estate, Bedwas, Caerphilly, Mid Glamorgan, tel:0292 086 8501.
True sensitivity depends on the size of the search coil. The smaller the search coil, the smaller the metallic particle that can be detected with maximum sensitivity.
When a radio signal is produced or transmitted by a metal detector, an electromagnetic field is generated that flows out from its search coil into the surrounding medium, whether it be air, cloth, skin, paper, leather, wood, concrete, or any other type of material.
