Hi hi, I'll explain everything in this topic, I want to made a fluxgate-magnetometer, to made it, I need connect a sin(w*t) wave to a selonoid (I ca get this from the AWG), then I get the output.
The magnetc flux if linearly dependant from the current, while due to the type of construction, we sould get the same voltage as the input (because we use the same numbers of turns in both places of the selonoid).
In order to make this work, I need to maximize the current and turns, and use a voltage that the osciloscope can measure, so, too low voltage will cause a voltage the osciloscope can't measure.
This requirements means, keep the wave generator working for a long time, without burn the osciloscope or the AWG, and be careful with the heat caused by the AWG.
A post I make and with some info is:
Thx to attila now we know the AWG can have aprox from 55mA/45mA, but as described, I don't know how much heat is generated in the osciloscope, or what are the power or current ranges that are secure for a long term usage...
I would like to know recomendations about this, and how to use the AWG safely?

The base concept to make one is:

While the magnetic flux of a selonid is:

The magnetc flux if linearly dependant from the current, while due to the type of construction, we sould get the same voltage as the input (because we use the same numbers of turns in both places of the selonoid).
