Science, 1986
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 magnetic tail. The detached bow shock wave in the solar wind supersonic flow was observed upstream at 23.7 Uranus radii (1 R U = 25 ...

Magnetic Resonance in Medicine, 1988
AbstractHomogeneous radiofrequency magnetic fields are necessary for production of high‐quality magnetic images and for most forms of magnetic resonance spectroscopy. It is often convenient to map the radiofrequency homogeneity associated with a resonant device by measuring the magnetic image intensity of an aqueous phantom placed within the resonator.

Fusion Technology, 1998
Plasmas and magnetic fields are inseparably related in numerous physical circumstances. This is not only the case in natural occurring plasmas like the solar corona and the earth magnetic tail, but also in laboratory plasmas like tokamaks and stellarators.

Interplanetary Magnetic Fields
Science, 1962Preliminary analysis of Mariner II magnetometer data indicates a persistent interplanetary field varying between a least 2 and 10 gamma (1γ = 10 -5 gauss). The interplanetary field appears to lie mainly in the ecliptic plane, although there is a substantial, fluctuating, transverse component.

Physical Review E, 2012
A vertically draining thin ferrofilm under the influence of gravity and a nonuniform magnetic field is considered. It is observed experimentally that the presence of the magnetic field greatly alters the drainage of the film. A mathematical model is developed to describe the behavior. Experiments are conducted for multiple magnetic field configurations.

Physica B: Condensed Matter, 1995
Abstract After a summary of the observations of cosmic magnetic fields, I briefly discuss the status of dynamos, the use of electric circuits, the physics of magnetic explosions, the role of magnetic tension and our strongest magnet known, the radio pulsar. Finally I mention a few problem areas which may show a breakthrough in the near future.

Magnetic Fields and Miscarriage
Epidemiology, 2002Is there a link between exposure to magnetic fields and the risk of miscarriage? Past epidemiologic stud? ies have been few and inconsistent,1,2 but with the publication in this issue of results from two large and sophisticated studies in Northern California,3,4 the ques? tion takes on a new level of interest.

Soviet Physics Uspekhi, 1960
Investigations and published data on strong magnetic fields and their applications are reviewed. Various means for creating strong magnetic fields with iron-core electromagn ets, with non-ferrous constant electromagnets, and the means for producing and measuring pulsed magnetic fields are discussed. 127 references. (R.V.J.)
