- Аннотация: A mechanism is proposed for the excitation of magnetic disturbances that induce secular geomagnetic variations with characteristic times of less than 100 years (e.g., 60-year variations). These disturbances have the form of concentrated flux ropes and loops generated by the fluctuation-type MHD dynamo in the earth's liquid core. The observed variations are caused by ropes situated in the 60-km-thick skin layer near the core-mantle boundary.
