Can magnets predict earthquakes?
Magnets are unrelated to Earth's magnetic field23. The Earth's magnetic field is extremely weak, with an intensity approximately 1/10,000 of that produced by a 2cm calibrated magnetic needle2. Although slight changes in Earth's magnetic field may occur before or after earthquakes, these variations are minuscule—amounting to less than 0.1% of the total geomagnetic field strength27.
