Once Ulysses was in its scheduled orbit, it began observing the solar wind and
magnetic field strength at high solar latitudes, finding that the solar wind from high latitudes was moving at about 750 km / s (slower than expected), and that there were large magnetic waves emerging from high latitudes which scattered galactic cosmic rays.
This diagram maps the temperature and
magnetic field strength at which the material's magnetoresistance turns on and then saturates.

at the time of the burning.
The researchers were able to alter the rate
at which they released the drops, and by changing the
strength of the
magnetic field they could also adjust the velocity of the drops.

strength of the
magnetic field being applied,» says Ben Evans, co-author of the paper and an associate professor of physics
at Elon University.
This receptor seems to measure the
strength of the
magnetic field — the
field is generally strongest
at the poles — and the angle of the
field in relation to the ground, which also varies with latitude.
Over time they build a more detailed
magnetic map by learning to recognise variations in the
strength and direction of the
field lines, which are angled more steeply towards the poles and flatter
at the
magnetic equator.
When the radio waves stop, the nuclei relax back to their original state, giving off a radio signal
at a frequency proportional to the
strength of the
magnetic field.

strength of the planet's
magnetic field measured
at Earth's surface.)
The frequency also correlates with the
strength of the
magnetic field; it is greater
at lower altitudes where the
magnetic field is stronger.
