I want to generate magnetic field around a coil.. For this am giving input a sinusoidal wave form from function generator. But the coil(18AWG cu) wire is not drawing much current as the coil has low resistance. When i calculated X and Z at different frequencies they are like this
freq: X : Z
100 0.00771 0.0775
1Khz 0.07669 0.1088
100Khz 7.51 7.51
1Mhz 74.03 74.05
how can i eliminate the problem of low resistance, i think it is acting as short ciruit.. while measuring in LCR meter i even found that my capacitance values are negative how it will happen like this? how can i achieve good field around the coil?
