Hello everyone , as for starters I would like to ask two questions. As i've been reading about the homopolar generator I have the basic understanding of all the workings yet here are my questions. Since the rotatig disc produces a current within while rotating in an axial magnetic field tipically shown coming from a round type permanent or electromagnet held stationary while the disc in wich the current is induced rotates , now since a current flowing in the disc creates a magnetic field around the disc itself , could the homopolar generator work without anything more than just a disc and two connections and once being spun a little kick start current once added would create a magnetic field which using the rotational energy from the disc supplied by an external force would continue to generate current ? like the same disc used for current generation would also be used for current induction as it would then become the rotor and stator at the same time and no real stator would be needed just a rotating disc , a little startup current and brushes for contacts would this work? also what would happen if I added a capacitor to the two outputs of the generator , wouldnt it become an generating oscillator because the current would flow only as long as the capacitor is charging and then stop so the b field would drop to 0 and the current generation would stop , then as the capacitor would discharge through the disc in the opposite direction a b field of opposite polarity would emerge and the disc would now generate in the opposite direction until again the cap is charged in the opposite polarity and so this would repeat in cycles as long as an external source of energy provides the rotational energy needed to spin the disc ?
