Problem Statement: I wish to make a current carring cable loop to generate a controlled magnetic field. http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/curloo.html
As I understand, the magnetic field generated depends on the Current in the loop and Loop radius (Fixed). I wish to maintain the current in the 50ohm loop to 25.3mA and 8mA respectively (ie. we have voltage of 1.26V equivalent to 12-13dBm and 0.4V equivalent to 2-3dBm).
I have a signal generator which can only support max RF output level of 13dBm.
I wish to have a cable diameter as large as possible so that the resonance frequency of the loop is higher. The operating frequency is below 7MHz.
As I understand the choosing a cable with higher cross section reduces the resistance and increases the power consumption. How can I determine the maximum cable core diameter (ie. thicker cable) for the loop cable so that I can maintain specified current levels in the loop with existing signal generator?
