The magnetic field experiment on the Voyager 2 spacecraft revealed a strong planetary magnetic field of Uranus and an associated magnetosphere and fully developed bipolar masnetic tail. The detached bow shock wave in the solar wind supersonic flow was observed upstream at 23.7 Uranus radii (1 RU = 25,600 km) and the magnetopause boundary at 18.0 RU, near the planet-sun line. A miaximum magnetic field of 413 nanotesla was observed at 4.19 RU , just before closest approach. Initial analyses… Expand

Plasma waves in the magnetotail of Uranus
As the Voyager 2 spacecraft left Uranus during its encounter with the planet on January 24, 1986, it passed through the magnetotail over the distance range of about 11 RU to 79 RU. During thisExpand
Magnetic field and current structures in the magnetosphere of Uranus
We compare Voyager 2 magnetic field and plasma data with theoretical model calculations for the magnetosphere of Uranus in order to derive a global picture from the quite limited set of measurements.Expand
Solar‐wind‐driven convection in the Uranian magnetosphere
We present an analytic, self-consistent model of time-dependent solar-wind-driven convection in the magnetosphere of Uranus. Because of the unusual orientation of the planetary rotation and magneticExpand
Electrostatic waves in the magnetosphere of Uranus
During its encounter with Uranus the plasma wave receiver on Voyager 2 observed electrostatic waves similar in many respects to those observed in other planetary magnetospheres. The most prominentExpand
Voyager 2 Radio Observations of Uranus
TLDR
Dynamically evolving radio events of various kinds embedded in these emissions suggest a Uranian magnetosphere rich in magnetohydrodynamic phenomena. Expand
Uranus' magnetic field and particle drifts in its inner magnetosphere
Both the Q3 model (dipole and quadrupole) and OCT model (Q3 plus octupole) of Uranus' magnetic field within 5 R U are expressed in α and β (Euler potentials) coordinate systems. By using the α and βExpand
The magnetic field of Uranus
A spherical harmonic model of the planetary magnetic field of Uranus is obtained from the Voyager 2 encounter observations using generalized inverse techniques which allow partial solutions toExpand
The magnetotail of Uranus
Voyager 2 observations have shown that Uranus possesses a well-developed bipolar magnetotail similar in certain characteristics to that of Earth, in spite of an anomalously large tilt of theExpand
Low‐energy plasma observations in the magnetosphere of Uranus
The plasma science experiment on Voyager 2 detected a large magnetosphere at Uranus containing a low-density plasma. All available evidence suggests the plasma is comprised principally of protons andExpand

The magnetosphere of Uranus - Plasma sources, convection, and field configuration
At the time of the Voyager 2 flyby of Uranus, the planetary rotational axis will be roughly antiparallel to the solar wind flow. If Uranus has a magnetic dipole moment that is approximately alignedExpand
Particle and field environment of Uranus
Abstract In 1985 the spin axis of Uranus points within 10° of the Sun and the planet's position is very near the solar apex direction. A Uranus mission with an encounter near 1985 might expect toExpand
Magnetic Field Studies at Jupiter by Voyager 2: Preliminary Results
TLDR
Results and the magnetic field geometry confirm the earlier conclusion from Voyager I studies that Jupiter has an enormous magnetic tail, approximately 300 to 400 RJ in diameter, trailing behind the planet with respect to the supersonic flow of the solar wind. Expand
Magnetic Field Studies by Voyager 2: Preliminary Results at Saturn
TLDR
V Voyager 2 crossed the magnetopause of a relatively compressed Saturnian magnetosphere at 18.5 RS while inbound near the noon meridian and throughout the outbound magnetosphere passage, the field was relatively steady and smooth showing no evidence for any azimuthal asymmetry or magnetic anomaly in the planetary field.

Plasma Observations Near Uranus: Initial Results from Voyager 2
TLDR
Extensive measurements of low-energy positive ions and electrons in the vicinity of Uranus have revealed a fully developed magnetosphere, with the boundary of the hot plasma component at L = 5 associated either with Miranda or with the inner limit of a deeply penetrating, solar wind-driven magnetospheric convection system.

Energetic Charged Particles in the Uranian Magnetosphere
TLDR
From the locations of the absorption signatures observed in the electron flux, a centered dipole model for the magnetic field of Uranus with a tilt of 60.1 degrees has been derived, and a rotation period of the planet of 17.4 hours has been calculated, providing independent confirmaton of more precise determinations made by other Voyager experiments.
