The excitation of Fast Magnetosonic (FMS) waves by a cylindrical array of parallel tethers carrying time-modulated current is discussed. The tethers would fly vertical in the equatorial plane. which is perpendicular to the geomagnetic field when its tilt is ignored. and would be stabilized by the gravity gradient. https://www.bekindtopets.com/hot-offer-Stuart-Product-Emcelle-Tocopherol-Vitamin-E-Liquid-1-Liter-hot-value/
