dc.description.abstract	The study presents the 3D electromagnetic model of layered isotropic and anisotropic media using an induction logging tool. This tool utilizes the electromagnetic wave frequency domain (EWFD) interface with Maxwell's equations. The study shows the effect of conductivity and depth for determining the electric field among single and multiple-layered formations. An induction logging tool operates deep inside the earth surface to measure earth formations and yields real-time formation parameters related to the layer of the earth as a function of depth. COMSOL Multiphysics software designs the induction logging tool, complex voltages are obtained from the 3D COMSOL model for the different layered formation, and MATLAB calculates attenuation and phase shifts. The induction tool is applied to both normal and horizontal directions in the formation to obtain electric fields and complex voltages. The method has an advantage of operating under complicated scenarios including one-, two- and three-layers without knowing the detailed properties.	en_US
