The Magnet Compass Research Paper

Many people believe that the magnetic compass is one of the most important inventions ever created, next to penicillin and the panini maker. It turns out that there is an entire story that lies behind this marvelous invention’s history and how it works. When most people think about a compass, they think of “that thing that shows which way is north”. But the truth is that it’s much, much more than that. This is an example of how much we take the things we have today for granted. Around 770-476 BC, Chinese miners found lodestone, a special rock that aligns itself with Earth’s magnetic field. Soon people realized that this rock could show direction, so they crafted the lodestones into a spoon shape and put them atop a flat, square shape bronze plate that represented Earth. Because of the material of lodestone, the pointy edge of the spoon always pointed south. The bronze plate itself had different characters that represented the different directions: north, south, east, west… At first, Chinese people used the magnetic compass to determine which way to place their deceased. The proper alignment of a dead body was and still is an important part of Chinese culture. The early compass was also used for people who performed Feng Shui, so they could align their furniture accordingly. The original magnetic compass was never actually used at sea due to its unsteadiness. Compasses weren’t brought to the ocean until it was discovered that a iron needle could be rubbed with lodestone and hung by a string to tell the direction. This new and improved compass allowed the Chinese to taking sea voyages as far as Africa. Even today, the compass is still a important tool for many people. For that, we owe a big thanks to the Chinese for creating such a wonderful invention. From now on, when looking at the small, versatile compasses of today, just remember that that little thing has come a long way from a spoon on a metal plate.

    Magnetic resonance imaging (MRI) use a rotating magnetic field, radio frequency pulses and a computer to create images of tissues, organs and the skeletal systems within a body. Radio waves redirect alignment of atoms that exist naturally within a body, as the atoms return to their usual alignment, they emit energy that varies depending on the type of body tissue they came from while the scanner captures the energy and created the image. Nikola Tesla discovered rotating magnetic fields in 1882 and…

    Compass- is a navigational instrument that shows directions in a frame of reference that is stationary relative to the surface of the earth. The frame of reference defines the four cardinal directions (or points) – north, south, east, and west. Intermediate directions are also defined. Usually, a diagram called a compass rose, which shows the directions (with their names usually abbreviated to initials), is marked on the compass. When the compass is in use, the rose is aligned with the real directions…

    Getting a good grade in geometry is very important, yet very hard to do if you cannot properly construct geometrical figures. Using a compass, a tool used to make arcs, and a straightedge; like a ruler, used to draw straight lines; helps students to properly construct figures. It is better to use a compass and straightedge to construct figures, than a drawing program online. One reason compasses and straightedges are important is that they are reliable. Using a drawing program, one might accidently…

    The Earth’s Magnetic Field This article will cover three large concepts about the Earth and its magnetic field. The first concept we will talk about is the fact the Magnetic North is NOT at the North Pole. This is because the magnetic North moves about a lot and does not always match up with the geographical north (the north pole). The diagram above shows us the difference between these two poles. The orange rectangle represents the giant ‘magnet’ inside the…
