In this Video, the principle of magnetic surveying in the different platform along with the glimpse of data acquisition, Processing and interpretation have been discussed in detail. The physics behind the basic principle of the magnetometer to detect magnetic anomaly has been meticulously illustrated for strengthening the basics of the viewers.

Hi
I am Dr Debajyoti Saha & Welcome to my YouTube Channel Physics, Geophysics learning
Step by step derivation and concept regarding the Electromagnetic Wave (EM) equation in the conducting medium has been presented in this lecture. Physics behind the attenuation of EM waves with skin depth has been given in detail. The idea and concept behind the phase lag between Electric and magnetic field have been presented in a very easy way. The application of the EM diffusion equation in the conducting medium has been given in the form of an Electromagnetic, Magnetotelluric (MT) Survey. A must watch for Physics, Geophysics People.
