EMF Meters and Ferromagnetic Interference

AI Thread Summary
Using an AC EMF meter to measure electromagnetic fields can be affected by the presence of ferromagnetic materials. These substances may interfere with the readings by altering the electromagnetic field. The exact impact of ferromagnetic materials on the measurements is not definitively established, indicating a need for further experimentation. The discussion highlights the importance of understanding the interaction between ferromagnetic substances and electromagnetic fields in physics. Overall, the inquiry reflects a genuine interest in exploring the complexities of electromagnetic measurements.

Hi,
My interest in physics is relatively new and recently I've been trying to figure out the answer to what is probably a simple question. Here it is; if one is using an AC EMF meter to read the time varying current from a man-made electromagnetic field, will brandishing ferromagnetic substances to the field effect or interfere with it at all? By this I mean, will the reading of the field be weakened by placing attracted substances between the electromagnet itself and the meter? Hopefully someone can help me with this.

Thanks,
Stoop

Yes.
 
Thank you

Thanks very much. That's all I needed to know.
 
Your question is directly indicating that you are interested in physics. Your question is based on experimental facts. No one can directly say that what will happen when ferromagnetic substances brandishing to the field. You are asking a good question and your question is related to http://www.yshield.com.au/emr-testing.html, I’ll also try to find the answer but if anybody knows please put here.
 
Thanks David

Thank you very much David,
This forum is very useful and hopefully your advice will help me to solve my problem, one way or another.
 
I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
