Web26 jan. 2024 · The Magnetic Pole started moving back in the 1800s, but always seemed to move and then bounce back and repeat. However, over the last 11 years, the magnetic pole has been moving very fast and is currently moving a rate of 5.25 miles ever 30 days! According to experts, past Pole Reversals happened every 12,000 years. Web1 okt. 2024 · Linear phase‐shifting transformers (LPSTs) are a new type of transformer that can be used in multi‐rectifier and multi‐inverter systems. However, calculating a precise magnetic field distribution in LPSTs, which is the key premise for obtaining accurate transformer parameters and performance evaluations, remains a challenging task.
