Eddy currents in what?I want to build an eddy current sensor.
Huh? Do you mean you have a coil wrapped around an air core? And maybe you want to measure magnetic field strength in that core?The square wave would have to create an emf in my air core.
Textbooks state that AC is not AC unless it swings below the 0V rail. So your 555 would be producing pulsating DC.Think of it this way can I create an emf in an air core inductor with an ac voltage...yes. Can I do the same with a square wave?
I don't think that AC maths will be applicable. AC is the hardest part of electronics. The level of maths is something that I do not have.Thanks for your responses and questions! @Alpha, I like where you're going. So if I pulsed positive then negative, this could work. Now how do you pulse negative? An inverter? Is this getting into a different thread?
