The loss of atmosphere is due to the twisted magnetic field, because of which the magnetosphere bounces “like a badly kicked soccer ball.” As a result, charged blisters of plasma, called plasmoids, BTA reported.
Scientists determined that the plasmoid around Uranus is 204,387 km by 402,336 km. It has drawn from 15 to 55 percent of the planet's atmosphere.
The magnetic field protects the planets by repelling the solar wind. According to NASA specialists, however, it also creates “funnels” through which to leak the atmosphere. This phenomenon was observed on Saturn and Jupiter. It's possible that Mars lost its atmosphere as well. Around Uranus, however, is specific.
"The axis of the magnetic field points 60 degrees to the side of the axis of rotation. Therefore, with the rotation of the planet, the magnetosphere jumps like a badly kicked ball”, explained by NASA.
This unique movement has attracted the attention of a team from the Goddard Space Center, led by Gina di Bracho. Scientists have extracted data over 34 years sent by Voyager 2". They showed the strength and direction of the magnetic fields near Uranus when the apparatus passed through. The plasmoid appears in just 60 seconds of Voyager 2"'s 45-hour flight off the planet.
It resembles a small deviation in the data, but recreated three-dimensionally resembles a cylinder.
Comparing the results with the plasmoids seen over Jupiter, Saturn and Mercury, specialists have estimated that the cylinder is at least 204,387 km long and 402,336 km wide. According to them, it contains charged particles, mostly ionized hydrogen.

NASA specialists re-analyzed data from the Voyager 2" spacecraft, which flew off planet Uranus in 1986, and found that its atmosphere was leaking through a massive plasmoid, reported in. The Daily Mail.tags:
