The strength of the Earth’s magnetic field ranges between 25,000 and 65,000 nano-Tesla (nT) with values of 31-58,000 nT between the equator and 50 degrees latitude.
Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...
Earth’s magnetic field is not fixed—it drifts, flips, and even weakens over time, altering navigation and planetary protection from solar radiation. Since its discovery in 1831, magnetic north ...
