Faraday winding

Tip We don t need to draw any current at all from this Faraday winding to make it work. So it need not even be required by our circuitry (for an auxiliary rail). In that case, we could just wrap a few turns of thin wire (spread out evenly), with one end of it connected to primary ground, and the other end via a small 22 pF capacitor to primary ground. This technique certainly saves production costs associated with the making and placing of a formal Faraday shield — not to mention the improvement in efficiency due to the reduced leakage inductance (as compared to what a formal Faraday shield may lead to). In that sense, this informal Faraday shield is a very useful idea, certainly worth trying out.

Henry, Joseph (1797-1878) US physicist, who became professor of natural philosophy at Princeton in 1832. In 1829 he made an "electric motor, and used insulated windings to produce a powerful "electromagnet A year later he iscovered "electromagnetic induction (independently of "Faraday), and in 1832 he discovered self-induction (seeinductance). In 1835 he invented the electric "relay.
