Understanding Electromagnetic Heating in Tissue: A Comprehensive Guide

AI Thread Summary
Electromagnetic heating in tissues can be approximated by knowing the conductivity and size of the tissue, allowing for simulations to predict heating effects. Finite-Difference Time-Domain (FDTD) simulations are commonly used to estimate absorbed power, particularly in studies related to cell phone radiation exposure. Resources such as Wikipedia on wireless energy transfer provide additional insights into the topic. Related discussions on physics forums can also enhance understanding of electromagnetic heating principles. Overall, accurate modeling of tissue heating due to electromagnetic radiation is feasible with the right parameters.

Is it possible to approximate the amount of heating in tissue (and other materials) due to electromagnetic radiation?
 
Physics news on Phys.org
Yes. If you knew the conductivity and size of your tissue you can easily do a simulation to predict the amount of heating. This is often done using FDTD simulations to estimate the amount of absorbed power by the human head from cell phones and such.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
