WitrynaThe magnet field produced by Earth is 0.5 gauss. 2 The magnet field produced by the magnet in a 1.5T MRI machine is 15,000 gauss, meaning the magnet in a 1.5T scanner is 30,000 times stronger than that produced by the Earth. The scanner uses this strength to align the hydrogen nuclei and produce the images for a MRI exam. Witryna16 lis 2024 · According to this article: The Earth's field ranges between approximately 25,000 and 65,000 nT (0.25–0.65 G). By comparison, a strong refrigerator magnet has a field of about 10,000,000 nanoteslas (100 G) The Earth's magnetic field is between 150 and 400 times weaker than a refrigerator magnet.
