Scientists at #Nagoya University 🇯🇵 are developing a low-cost 💴 system to measure and observe #SpaceWeather entirely from the ground using magneto-impedance sensors. Currents ⚡ generated by ionized particles flowing in the #magnetosphere tens of thousands of kilometers above Earth produce magnetic 🧲 field variations, the effect can be observed in the changes in the magnetic field on Earth 🌏 https://spectrum.ieee.org/space-weather
