RD-10629 Abstract of the Disclosure A lamp ballast has a pair of adjacent gapped "0" magnetic cores made of nested, almost complete loops of amorphous metal strip with the gaps in the loops shaped and arranged under the secondary coil to simulate any type of restricted cross section for shaping the lamp current. A long slender reactor has a similar configuration in which the gaps are staggered; a different embodiment has a long central core of compressed amorphous metal flake and a helical overwrap of ribbon. An alloy of iron, boron, and silicon with a high Br/Bs ratio is preferred for these inductive devices.
