Magnetic declination, sometimes called magnetic variation, is the angle between magnetic north and true north. As the compass points with local magnetic fields, declination value is needed to obtain true north..
We therefore need a record of how the position and strength of the Earth's magnetic field has changed over time. The record of how the field has changed is referred to as a secular variation curve and is used to calibrate the measured information to obtain a calendar date (Clark et al. Since every substance is made up of charged particles, these substances rotating about an axis is equivalent to a circulating current and hence is responsible for the Earth's magnetisation. As the earth rotates, strong electric currents are set up due to movement of charged iron (due to showers of cosmic ray). The earth's magnetic field has an axis which is inclined 20o west of the axis of rotation of earth.
To describe the magnetic field of earth at any place three quantities or elements are required. The angle between the direction of total intensity of Earth's field with the horizontal line in magnetic meridian. Horizontal component is the component of the total intensity of Earth's magnetic field in the horizontal direction in magnetic meridian.

NASA is looking for a talented and enthusiastic team player to join our WorldWind development team (Android, JavaScript, Java). This addon shows the isogonic contours of earth's magnetic declination and an intensity map. Cool, I did the samething a while back with a shapefile I got from National Geophysical Data Center.
I can add more contours, but to get the coloring and labeling they have to be generated individually. I also have a problem on my computer with some contours vanishing when the point of view is near the equator. Does anyone here think it is possible to just make the measure tool output declination in magnetic instead of grid?
You would just need code that returned declination for a given latitude and longitude (not just plotting lines like this add-on does).
Identify grazing animals using Google Earth and determine if they have aligned themselves with Earth's magnetic field. Recently, research has suggested that large mammals, such as deer and cows, do, in fact, have the ability to sense Earth's magnetic field.
In this zoology science project, you will investigate the alignment of cattle, sheep, horses, or other large mammals. This is an advanced research-based science fair project that will take a lot of time and effort. What are some examples of other senses that appear to be absent in humans, but that are present in other living things?
Based on your research, what experiments have been done to show that homing pigeons can sense Earth's magnetic field?
Tip: If the images were taken after 2006, there may not be grazing animals at the location given, but if you look at an older picture of that location, or search around within that pasture (or nearby pastures), then you will likely find grazing animals. If a pasture has to be broken up into several PowerPoint slides, label the slides appropriately. The next step will be to determine the angle between magnetic north, which you just drew on the image, and the axis of each animal in the image.
Since you are not recording which way the animal is facing (since you may not be able to distinguish head from tail), do not use a full circle of 360 degrees.


A value of +7, for example, would represent an axis slightly to the right of magnetic north. In your lab notebook, record the angular values you found for each pasture (also record the latitude, longitude, and country) in a data table (one column per pasture). Is there a clear trend for the animals to align themselves with the magnetic field of Earth?
In order to determine how strongly the data supports the theory that the animals are aligned in a north-south axis, you will have to perform some statistical analysis of the data.
If grazing animals do align themselves with the magnetic field of Earth, are there certain geographic features that can disrupt this alignment, such as the presence of high-voltage power lines in the area? Compared to a typical science class, please tell us how much you learned doing this project. The Ask an Expert Forum is intended to be a place where students can go to find answers to science questions that they have been unable to find using other resources. Ever wondered what wild animals do all day, where a certain species lives, or how to make sure a species doesn't go extinct? Statisticians use the power of math and probability theory to answer questions that affect the lives of millions of people.

Specific events can cause the magnetic materials to record information about the direction and strength of the magnetic field. But recently it has been discovered that some migrant birds have magnetic sensors in their heads, which help to guide them using the Earth's magnetic field. The north pole of this huge magnet must be towards geographic south as to attract South Pole of the suspended magnet. These points are those where magnetic field of the bar magnet cancel with that of Earth's field. Everyone who signs up gets full access to our entire library, including our curated collections.
Our Standard license allows you to use images for anything, except large print runs over 500,000+ or for merchandising. Once you have downloaded your image, you have life-long rights to use it under the terms of the license purchased. But in addition to the senses of touch, smell, taste, hearing, and sight, some animals are able to sense Earth's magnetic field. Sabine Begall, who generously provided latitude and longitude coordinates, and contributed information for the procedure. You will have to use a lot of creative problem solving and self-guided research to complete the project. It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results! Copy and paste these coordinates into the "Fly to" box in Google Earth to see the grazing animals. Note: You can change the date of the picture by clicking on the year shown in the box in the bottom left corner of the screen. Before the project, I would not have even taken a second glance at the cows on the side of the road.
If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help.
Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They tell educators which teaching method works best, tell policy-makers what levels of pesticides are acceptable in fresh fruit, tell doctors which treatment works best, and tell builders which type of paint is the most durable. If we know how the magnetic field has changed over time, and we can measure the information held within the magnetic minerals about the past magnetic field, we can produce a date. A freely suspended magnet has its north pole pointing towards geographic north; we therefore designate the earth's magnetic pole close to geographic north as magnetic south. The pointed ends move over the graduations on the scale, which are marked 0-0 in the horizontal and 90-90 in the vertical directions. These particles ionise the atmosphere above these poles which display a light high up in the atmosphere.

Sabine Begall, and colleagues in Germany and the Czech Republic, published a paper in the Proceedings of the National Academy of Sciences (PNAS), entitled "Magnetic alignment in grazing and resting cattle and deer" (see the Bibliography for details).


Geographic north is the direction you would travel to get to the northern axis of Earth's rotation. For the purposes of this science fair project, you should ignore the fact that the declination is changing with time.
Now, after the project, I say every time I see cattle, they're all facing the same way and I know why.
Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. They study the behaviors and habitats of wild animals, while also working to maintain healthy populations, both in the wild and in captivity.
They are employed in virtually every type of industry imaginable, from engineering, manufacturing, and medicine to animal science, food production, transportation, and education.
This phenomenon occurring in the arctic region is called aurora borealis or northern lights and in south it is called aurora australis. But other animals have developed different kinds of senses that are not (as far as we know) used by humans. It is important to be clear that the orientation of grazing animals that was investigated was not due to other factors. It is often not possible to tell which side of the animal is the head and which side is the rear, so you will just determine the direction of the long axis of their bodies. The compass shows the approximate bearing of the magnetic north, where the red arrow points toward magnetic north.
The basalt from volcano cools and solidifies and provides the picture of earth's magnetic field.
New research suggests that large mammals, such as cows and deer, may also have the ability to sense the direction of magnetic north. These other senses include echolocation, infrared vision, electric sense, and magnetic sense.
For example, cattle stand perpendicular to the sun on cold, sunny days, especially in the early morning, maximizing the surface area exposed to sunlight and gaining heat. If you choose to find and analyze your own herds of animals, you will be providing new data in this exciting area of research! As the basalt can be dated back, a clear picture of the earth's magnetic field has emerged. In this animal behavior science project, you will put this theory to the test and use Google EarthTM to find herds of grazing animals, then analyze their orientation to see if they are aligned with the local magnetic field. Echolocation is used by bats and whales to determine the location and speed of things in their environment. On the other hand, cattle orient parallel with strong winds during winter, which minimizes the area exposed to heat loss associated with wind. If the area under study has a declination of 10 degrees east, the direction that a compass needle points is "off" by 10 degrees from true geographic north. Infrared vision is used by certain kinds of snakes to identify warm-blooded prey in low-light conditions. But the paper claims that when other factors are not present, cattle and deer align themselves with Earth's magnetic field. The direction of true north in this case is 10 degrees west of north, as indicated by the compass needle. Certain kinds of fish are able to create an electric field (the electric sense), which can be used to detect environmental cues in murky water. Beyond basic research, biologists might also apply their research and create new biotechnology. And finally, magnetoreception is the ability to detect a magnetic field to perceive direction, altitude, or location. This sense is used by a surprising number of animals, including honeybees, sharks, sea turtles, rays, homing pigeons, migratory birds, tuna, and salmon. Note that the procedure uses a slightly different way of recording the angles of the animals than the one found in Begall's paper.
The question of whether large mammals are capable of magnetoreception has been controversial. In the paper, the angles of the axes are recorded relative to geographic north and then corrected for declination. In the procedure for this science project, the angles of the axes are taken relative to the local magnetic north.
