Quark nuggets are theoretical objects composed of approximately equal numbersof 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 ${\sim}85\%$ ofmatter. Most previous models of quark nuggets have assumed no intrinsicmagnetic field; however, Tatsumi found that quark nuggets may exist inmagnetars as a ferromagnetic liquid with a magnetic field between $10^{ 11}$ Tand $10^{ 13}$ T. We apply that result to quark nuggets, a dark-mattercandidate consistent with the Standard Model, and report results of analyticcalculations and simulations that show they spin up and emit electromagneticradiation at ${\sim}10^{ 4}$ Hz to ${\sim}10^{ 9}$ Hz after passage throughplanetary environments. The results depend strongly on the value of $B_{o}$,which is a parameter to guide and interpret observations. A proposed sensorsystem with three satellites at 51,000 km altitude illustrates the feasibilityof using radio-frequency emissions to detect 0.003 to 1600 MQNs, depending onBo, during a five year mission.
