Magnetic field in Earth by Hugo https://padlet.com/sciencehmdjs/966x0y1w1mrr5r9y en-us 2023-05-12 13:59:46 UTC 2023-06-06 09:17:59 UTC hello@padlet.com Why is Earth's magnetic field so powerful? swali11 https://padlet.com/sciencehmdjs/966x0y1w1mrr5r9y/wish/2588766371
Scientists know that today the Earth's magnetic field is powered by the solidification of the planet's liquid iron core. The cooling and crystallization of the core stirs up the surrounding liquid iron, creating powerful electric currents that generate a magnetic field stretching far out into space.

While some scientists estimate the field's strength might completely decay in about 1,300 years, the current weakening could stop at any time.
