Hi, everyone.
I'm working on a project right now where I need to amplify an AC signal to create as much current as possible in a solenoid to generate as strong a magnetic field as I can. I'm likely dealing with a maximum of 10 V and 10 mA from my signal generator, but I ideally need a peak current in the range of several amps. My solenoid is thick-gauge wire and can likely handle the current (we're also looking at cooling options in case the inside gets too hot), but with my limited background in electronics, I'm at a bit of a loss on effective techniques for current amplification. Some ideas I've explored are building a parallel RLC circuit (a resistor in series with the solenoid and a resistor in series with the capacitor) and driving it at resonance or amplifying the power with an op-amp or a transistor and then stepping up the current with a transformer. However, to be brutally honest, I don't have much experience with this scale of amplification, and I don't have a fantastic idea of what I'm really doing.
Do you guys have any recommendations for amplifying small signals into large ones?
