Uranus has a weird magnetic field that's stumped scientists for 40 years — we may finally know why

Scientists have been grappling with the unusual magnetic fields of Uranus and Neptune for four decades, seeking to understand their perplexing shapes. Recent research suggests these tilted fields are likely caused by intense electrical currents within the planets themselves. These currents arise from extreme conditions deep inside the planets, specifically boosting the planet’s electrical conductivity. This enhanced conductivity then dramatically strengthens the dynamo effect, which is responsible for generating planetary magnetism. The discovery offers a potential explanation for why Uranus's magnetic field is so significantly offset from its rotational axis, aligning it almost perfectly with the planet’s orbit.
