When strong solar storms are diverted poleward by our magnetic fields we often observe in the ionosphere?
When strong solar storms are diverted poleward by Earth's magnetic fields, they can lead to the formation of auroras, commonly known as the Northern and Southern Lights. This occurs as charged particles from the solar wind interact with the ionosphere, exciting gas molecules and causing them to emit light. Additionally, these storms can disrupt radio communications and GPS signals, as well as affect satellites and power grids on Earth. The resulting ionospheric disturbances can lead to increased ionization and variability in the upper atmosphere.

What is a possible cause of solar prominences?
Solar prominences are caused by the interaction between the Sun's magnetic field and plasma gases on its surface. When the magnetic field lines become twisted or tangled, it can lead to the eruption of plasma, creating the beautiful and dynamic solar prominences that we observe.
What is te correct verb form of observe?
Observe is a verb
What is the probe that was launched in 1990 to study the sun's poles?
The Ulysses probe was launched in 1990 to study the sun's poles. It provided valuable data on the sun's magnetic field, solar winds, and other phenomena at high solar latitudes that are difficult to observe from Earth.
What do we observe?
the world
What 2 things can't the Hubble observe?
Hubble cannot observe objects smaller than a basketball on the moon or detect dark matter directly.
How can you use iron fillings to show the shape of a magnetic field?
You can sprinkle iron fillings near a magnet to observe the pattern of the magnetic field. The iron fillings will align along the magnetic field lines, making the shape of the magnetic field visible. This technique helps visualize the direction and strength of the magnetic field.
How do scientists detect the presence of magnetic fields if they are invisible?
Scientists detect the presence of magnetic fields using instruments called magnetometers, which can measure the strength and direction of magnetic fields. These instruments can detect the effects of magnetic fields on nearby objects or particles, allowing scientists to indirectly observe and study them.
When the solar wind collides with the earth's magnetic field what do we observe?
The Aurora's.Northern Hemisphere - Aurora borealisSouthern Hemisphere - Australis borealis
Do sunspots occur in magnetic pairs?
Yes, sunspots typically occur in pairs with opposite magnetic polarities. This is known as Hale's polarity law. Sunspots are regions of intense magnetic activity on the Sun's surface, and the interaction between these magnetic fields gives rise to the characteristic dark spots we observe.
What happens in earth interior to produce earths magnetic field describe the layer where the magnetic field is produced?
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.

How can you show that a given bar is a magnet?
The following two methods are really the same idea:1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.Another method:3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.
Why can we not be certain about how the earth's magnetic field works?
The Earth's magnetic field is generated by complex interactions in the outer core, which we cannot directly observe or replicate in a lab. Additionally, the field is influenced by dynamic processes in the planet's interior, making it challenging to predict with absolute certainty.

How is the angle of magnetic declination measured?
You need to determine the geographic north, for example by observing sunrise and sunset; by observing the stars; or by using a compass that reacts to Earth's rotation (a gyrocompass). Then you observe where the needle of a magnetic compass points. Finally, you measure the angular difference between the two.
What will you observed when A magnet is rolled in a mixture of iron filling and sulfur powder?
The iron filings will be attracted to the magnet and stick to it due to their magnetic properties. The sulfur powder will remain unaffected as it is not magnetic. You will observe the separation of the iron filings from the sulfur powder as the magnet is rolled through the mixture.
What do you observe about the direction of field lines at N poles?
At the north poles of a magnet, the magnetic field lines emerge and point outward, indicating the direction in which the magnetic force would act on a positive magnetic charge. This means that the field lines are directed away from the north pole and curve around to enter the south pole. The density of these lines also indicates the strength of the magnetic field, with closer lines signifying a stronger field.
