| Popis: | Quark nuggets are theoretical objects composed of approximately equal numbers of up, down, and strange quarks. They are also called strangelets, nuclearites, AQNs, slets, Macros, and MQNs. Quark nuggets are a candidate for dark matter, which has been a mystery for decades despite constituting ${\sim}85\%$ of matter. Most previous models of quark nuggets have assumed no intrinsic magnetic field; however, Tatsumi found that quark nuggets may exist in magnetars as a ferromagnetic liquid with a magnetic field between $10^{ 11}$ T and $10^{ 13}$ T. We apply that result to quark nuggets, a dark-matter candidate consistent with the Standard Model, and report results of analytic calculations and simulations that show they spin up and emit electromagnetic radiation at ${\sim}10^{ 4}$ Hz to ${\sim}10^{ 9}$ Hz after passage through planetary environments. The results depend strongly on the value of $B_{o}$, which is a parameter to guide and interpret observations. A proposed sensor system with three satellites at 51,000 km altitude illustrates the feasibility of using radio-frequency emissions to detect 0.003 to 1600 MQNs, depending on Bo, during a five year mission. 31 pages, 9 figures, 4 tables, submitted to Scientific Reports. arXiv admin note: text overlap with arXiv:2004.12272 (as referenced by authors).
