Mar 21, 2023 at 3:45 comment added moonblink Thank you, Mauricio. Finally I can compare the actual strength of Earth's magnetic field (8×10²² A m²) with that of a small neodymium magnet (0.422 A m²). I wonder why people still measure the strength of magnets using teslas (which cannot really capture the strength of magnets)…
