Text__Q76kcKObEd-WfYQ0GneCwQ_text=<p>Einstein asks Schr\u00F6dinger to scrutinize empirical evidence to determine whether the magnetic field of the Earth is symmetrical. He assumes that this field is induced by electrical currents. Such currents in the Earth\u2019s crust would generate an asymmetrical field, because of the high conductivity of the oceans. Currents in the Earth\u2019s core would generate a symmetrical one.</p>
