Texts and descriptions are fine and dandy, but to see planet Earth for what it is is another thing altogether. Wait, so according to your theory, Pongo, planes should fly at very low altitude too to use less fuel, right? Such space weather events cause auroras and, when very strong, can produce radiation events that could cause our satellites to fail.
Now, special cameras aboard the Interstellar Boundary Explorer, or IBEX, spacecraft have snapped the first shots of this complex space environment. The white lines show a model of where magnetic field lines are expected in Earth's magnetic atmosphere. But when they looked closely, the group realized they didn't only have a picture of a quiescent plasma sheet. Because researchers believe this phenomenon generally occurs deeper in the magnetotail, the IBEX team is considering other explanations for the event, as well. A computer-generated image of IBEX and its two imagers specialized to detect neutral atoms in Earth's magnetic field and out to the edges of the solar system to provide images of space that cannot be photographed with traditional cameras. IBEX is the latest in NASA's series of low-cost, rapidly developed Small Explorers spacecraft. The objective of this science fair project is to demonstrate eddy currents and induced magnetic fields. Factors that increase the effect of eddy currents include stronger magnetic fields, faster-moving magnetic fields, and thicker conductors. We also do our best to make sure that any listed supplier provides prompt, courteous service. Proceeds from the affiliate programs help support Science Buddies, a 501(c)(3) public charity. Scientists do multiple trials and calculate an average to help even out any errors in their experiment.
To calculate the average, add up the values, and divide by the number of trials (in this case, 3).
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. Just as a potter forms clay, or a steel worker molds molten steel, electrical and electronics engineers gather and shape electricity and use it to make products that transmit power or transmit information.
Physicists have a big goal in mind—to understand the nature of the entire universe and everything in it!

This combined with the fact that their mass is vastly greater than a birds may benefit them to fly higher to distance themselves from earth's weak gravitational pull.
The jellyfish "tail" is known as the magnetotail and it flows off to the right in this picture, away from the sun on the "night side" of Earth. But until now no one has been able to take pictures of these fascinating processes in the plasma sheet. Instead of recording light, these two large single-pixel cameras detect energetic neutral atoms.

The Southwest Research Institute developed the IBEX mission with a team of national and international partners.
A magnet is a material that produces a magnetic field, which can exert a force on other materials without actually touching them. In 1834, while investigating magnetic induction, he noticed and described an interesting phenomenon.
Factors that reduce the effect of eddy currents include weaker magnets, slower-moving magnetic fields, and non-conductive materials.
You will accomplish this by sending a neodymium magnet down a conductive tube and then down a non-conductive tube. It's not as smart as you are, and it may occasionally give humorous, ridiculous, or even annoying results! Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. If you need to separate neodymium magnets, they can usually be separated by hand, one at a time, by sliding the end magnet off the stack. Neodymium magnets are brittle and may crack or shatter if they slam together, possibly launching magnet fragments at high speeds. Hold the pipe near the top with one hand, and have the volunteer hold the pipe near the bottom so it does not shake.
You will need to start the stopwatch as soon as you let go of the magnet, and stop the stopwatch as soon as the magnet exits the bottom of the pipe. For example, in this experiment, there could be some human error in how fast you hit “start” and “stop” on the stopwatch. Make a bar graph with the type of pipe (copper or PVC) on the horizontal, and the average fall time on the vertical axis. Does the time it takes for the magnet to fall down the tube decrease, increase, or remain the same? If you have specific questions about your science fair project or science fair, our team of volunteer scientists can help. Electrical and electronics engineers may specialize in one of the millions of products that make or use electricity, like cell phones, electric motors, microwaves, medical instruments, airline navigation system, or handheld games.
To reach that goal, they observe and measure natural events seen on Earth and in the universe, and then develop theories, using mathematics, to explain why those phenomena occur. As long as you can produce enough lift, it will be easier to fly as high as possible than at ground level. NASA's IBEX mission recently captured the first images of the magnetotail and the plasma sheet. Magnetic field lines pull apart and come back together, creating explosions when they release energy. Such fast-moving atoms are formed whenever atoms in the furthest reaches of Earth's atmosphere collide with charged particles and get sent speeding off in a new direction. Since its October 2008 launch, the IBEX science mission has flourished into multiple other research studies as well. This means that the carriage of the train is suspended over the rails with no support, but only with magnetic fields! A magnetic force can attract or repel, and some materials can exert a larger force than others.
This phenomenon is now called Lenz's law and it occurs when a magnet interacts with a conductor. Optionally, you can use something like duct tape or zip ties to fix the pipe in a vertical position (for example, by attaching it to the leg of a table).


Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.
Physicists take on the challenge of explaining events that happen on the grandest scale imaginable to those that happen at the level of the smallest atomic particles.
The Earth can be, round, flat, cubic, toroidal or whatever you want it to be, and the birds would still fly at that altitude. However, from my limited understanding of planes, I understand it's very dangerous for them to fly at lower altitudes. Disconnected bits of the tail called "plasmoids" get ejected into space at two million miles per hour. Called Energetic Neutral Atom or ENA imaging, the technique captured unprecedented images of the plasma sheet. In addition to supporting magnetospheric science, the spacecraft has also directly collected hydrogen and oxygen from the interstellar medium for the first time and produced the first ENA images of the outer edges of the bubble surrounding the Sun, called the heliosphere. There is a physical explanation for magnetic levitation, and if you would like to learn more about magnetism and current, this is a science fair project that you must try! A conductor is a material that permits electrons (and therefore electricity) to flow through it easily.
Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy. They fly high because the thinner air reduces drag, it has very little to do with danger and nothing (at all) to do with gravity. This means that a conductor has a low resistance and resistivity to the motion of electrons.
Then, using your body weight, hold the stack of magnets on the table and push down with the palm of your hand on the magnet hanging over the edge. Russel Close to the globe, Earth's magnetic field wraps around the planet like a gigantic spherical web, curving in to touch Earth at the poles. When a magnetic field varies along the length of the conductor, like when you let go of a magnet down a metal tube, the magnetic field induces a current within the conductor. Just be careful that they do not snap back together, pinching you, once you have separated them. As you move to the high altitudes where satellites fly, nothing about that field is so simple. The magnet's poles (such as Earth's north and south poles) are where the magnetic field begins and ends. Instead, the large region enclosed by Earth's magnetic field, known as the magnetosphere, looks like a long, sideways jellyfish with its round bulb facing the sun and a long tail extending away from the sun.
If you look at the magnetic field of Earth, you will notice that the magnetic field is not straight.
This induced magnetic field opposes the magnetic field of the magnet that is moving along the conductor. As a result of two opposing magnetic fields, the magnet will stop moving and float, or levitate.
This is the principle behind the world's fastest trains, called magnetic levitation (maglev) trains.
