I have a solenoid where I'd like to vary the current. I would guess since the solenoid's coil resistance is fixed that'd mean that I vary the voltage since:
V=IR
So what/how would I do this. I would guess it's going to be high current since the coils DC resistance is only 6 ohms.
Would PWM from a uC and a MOSFET be a good way to make this work?
