This class includes measurement of electrical resistivity (ER) or conductivity (EC), time domain reflectance (TDR), frequency domain reflectance (FDR), ground penetrating radar (GPR), and electromagnetic induction (EMI). 2.2.1 Electromagnetic induction The EMI sensors are based on Faraday's la...
When current passes through a wire it generates a magnetic field. Similarly, if a changing magnetic field passes through a coil, an emf appears in the coil. This phenomenon is called electromagnetic induction Exp. To demonstrate electromagnetic induction (a) coil and magnet (b) coil and coil-o...
and does not include active electronic components which could be affected by such disturbances. Most electronic equipment could not be regarded as benign, since it wouldn’t meet one or both of these criteria, but some simple electrical apparatus such as switches, fuses,induction motorsandfilament ...
4 denotes a line of electromagnetic induction which is generated in the electromagnetic clutch 10 via the armature 18. More specifically, before the armature 18 is magnetically attracted to the rotor 16, the ring member 19 is free from a pressing force of the armature 18. In other words, ...
Electromagnetic (EM) imaging aims to produce large-scale, high-resolution soil conductivity maps that provide essential information for Earth subsurface ex
22568/57. Class 38 (2). An electromagnetic induction device comprises a winding 10 on a wound magnetic core 14 which is enclosed in a frame 18 provided with slots 38 through which passes a closure member 20, whose ends 22 are bent to abut the frame and secure the parts of the device....
if the diametrically opposite polar coils are coupled with additive flux, and it easily crosses the cylindrical coils of the induction winding 8, whose turns form a magnetically pervious horizontal layer, to stir by rotation the liquid core 10 of the billet 15 during a continuous casting process...
My invention relates to electromagnetic induction apparatus such as transformers, and although not limited thereto, it has particular application to a current transformer structure having windings con
An electromagnetic induction coil includes a casing with high magnetic permeability with a magnet disposed within the casing. The magnet has a central hole. A core with high magnetic permeability is d
