Just a hint: You may be able to "model" a pacemaker's EMR sensitivity with several coils of wire of different size (for different frequency ranges), each with a simple detector circuit. You, after all, don't have to fully characterize the EMR, just detect that it's present in a given band and abo

Hi Bob, Thanks for your reply. We are working on a master project, where we want to detect the magnetic radiation signals, which would affect the patients with Pacemaker devices. Thus, magnetic radiations may be ranging from very mild to maximum intensity. The wavelength would not be in too many

Your problem statement is too vague to be useful. I don't mean so much useful to us, as useful to you. You really need to be a great deal more specific about what you want to sense. The term "electromagnetic radiation" covers a range from signals with wavelengths many orders of magnitude larger th
