網頁2024年4月19日 · During this period, it’s entirely possible that the Earth had a magnetic field of sorts, due only to whatever residual magnetism was frozen into the rocks as the Earth solidified. That changed, rather abruptly actually, about a half-billion after the Earth formed – a little more than 4 billion years ago.
