... 5. Why do ferrofluid materials behave differently than bulk magnetic materials? Ferromagnetic particles within the fluid specifically align with the external magnetic fluid making a dome shape with or without spikes. The spikes are a result of the strong magnetic lines in that particular direction a ...

... west direction. What is the direction of magnetic field at a point directly below it and at a point directly above it? Solution The current is in the east-west direction. Applying the right-hand thumb rule, we get that the direction of magnetic field at a point below the wire is from north to south. ...

For a given CA II K-line index there are too few sunspots
... The Plage index is MWO’s Magnetic Plage Strength Index MPSI: For each magnetogram taken at the 150-Foot Solar Tower, a Magnetic Plage Strength Index (MPSI) value is calculated. To determine MPSI we sum the absolute values of the magnetic field strengths for all pixels where the absolute value of the ...

... Why is the aurora borealis visible from some parts of the world and not others? We’ve learned that an aurora borealis occurs when particles from the sun’s solar winds hits the Earth’s atmosphere at an angle and this can only happen at the poles of the Earth.

Compass
A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal directions, or ""points"". Usually, a diagram called a compass rose, shows the directions north, south, east, and west as abbreviated initials marked on the compass. When the compass is used, the rose can be aligned with the corresponding geographic directions, so, for example, the ""N"" mark on the rose really points to the north. Frequently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270. These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation.The magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since about 206 BC), and later adopted for navigation by the Song Dynasty Chinese during the 11th century. The use of a compass is recorded in Western Europe and in Persia around the early 13th century.
