Sentences with phrase «magnetic field strength at»

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 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.
