Professor: Okay, keep in mind that solar wind is electrically charged, which means that it interacts with the magnetic field as electromagnetic theory tells us.Okay, how does it interact?Earth, magnetic field deflects most the solar wind, makes it flow around the earth without getting very clo...
In the study of the Earth's interior, magnetic field data is also used. How does the Earth's magnetic field help in understanding the Earth's interior? A. It has no relation to the Earth's interior structure. B. It can only tell us about the surface temperature. C. Changes in the ...
Life as we know it could not exist without Earth's magnetic field and its ability to deflect dangerous ionizing particles from the solar wind and more far-flung cosmic rays. It is continuously generated by the motion of liquidironin Earth'souter core, a phenomenon called the geodynamo. Despit...
Q: How does Earth’s magnetic field protect us? Q: If a long hot streak is less likely than a short hot streak, then doesn’t that mean that the chance of success drops the more successes there are? Q: Where do the rules for “significant figures” come from? Q: If time slows do...
Most often used for geomagnetic measurements are the fluxgate magnetometer, which gives vector components, and the proton precession magnetometer, which measures field intensity.Auster, HUPhysics TodayH.-U. Auster, How to measure Earth's magnetic field. Phys. Today 61(2), 76 (2008). ISSN:...
s magnetic field at the time they are formed. Analysis of the crystals showed that, at their point of formation, the Earth’s magnetic field was the weakest ever recorded — some 30 times weaker than both the current magnetic field intensity, and that measured from similar crystals formed ...
A compass in the vicinity of a magnet will always point along a tangent to one of the magnetic field lines. This occurs because unlike poles of a magnet are always attracted to each other by the invisible lines of force whereas like poles repel each other. The earth acts like a large pe...
When you realize that the Earth's magnetic field measures 0.5 gauss, you can see how powerful these magnets are. Most MRI systems use a superconducting magnet, which consists of many coils or windings of wire through which a current of electricity is passed, creating a magnetic field of up ...
For a stronger magnetic field, the wire should be more tightly wrapped. What is an electromagnet and how does it work? Electromagnets create a magnetic field through the application of electricity. When you introduce the current, either from a battery or another source of electricity, it flows...
3. What creates the Earth's magnetic field (and why does it move)? 3.是什么创造了地球的磁场(为什么它会移动)? 4. Will we be able to predict catastrophic weather events (tsunami, hurricanes, earthquakes) more accurately? 4.我们是否能够更准确地预测灾害性事件(海啸、飓风、地震)?
