Helix Oxford Metal Compass & Pencil, Black

Product Information

Which end of a magnet will the north pole of a compass point towards when it lines up with the magnetic field?

Very early compasses were made of a magnetized needle attached to a piece of wood or cork that floated freely in a dish of water. As the needle would settle, the marked end would point toward magnetic north.Triangulate your position. Draw a line along the compass' edge and through your approximate position. This is the first of three lines you will draw to find your position by forming a triangle with the other two landmarks.

At STAEDTLER, our product range includes a large selection of high-quality compasses. Our models are particularly sturdy, providing the ideal basis for creating precise drawings at school and in professional applications. We offer products that meet various requirements, from solid metal to sturdy plastic/metal designs. Our compasses are also available in compact sets with practical accessories. Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a pen. If a breeze hits the compass, it may have trouble aligning itself north to south. Try to shield the compass from wind by using a deeper jar or bowl. One of the most important features of a permanent magnet, whatever shape it is, is that it has two different ends. These ends are called poles . There is a north (N) pole and a south (S) pole.The school compasses (models 550 50, 550 55, 550 60, 559 WP 00) in our product range are specifically designed for younger children. These extra-safe precision compasses have a blunt safety needle to prevent injury.

Maps were able to be created thanks to the compass. It even helped establish the fact that the Earth is a globe and not flat. Close to the poles the particles are able to reach the atmosphere. This causes the air to light up in a display called the Aurorae .

Understand the basic layout of the compass. While the designs of compasses are different, all compasses include a magnetized needle that orients itself to the magnetic fields in the Earth. The basic field compass, also sometimes called a baseplate compass, features the following simple components you should familiarize yourself with as soon as possible: [1] X Research source Scientists and historians don’t know when the principles behind magnetic compasses were discovered. Ancient Greeks understood magnetism. As early as 2,000 years ago, Chinese scientists may have known that rubbing an iron bar (such as a needle) with a naturally occurring magnet, called a lodestone, would temporarily magnetize the needle so that it would point north and south. Who could forget the compass that’s used in mathematics? A handy tool that helps to aid with drawing circles and other geometric shapes as well as finding mid-points to help solve problems. Not related to Earth’s magnetic field but still a compass worth mentioning. In the 12th century, as early scientists discovered more about magnetism, the compass needle was placed on a pin, and in the 13th century added in the compass cards. At first this compass card showed only the main four cardinal directions, but over time this design evolved to show 32 directional points. The main use for compasses were out at sea, as there are no landmarks to help with navigation. Sailors used to use the stars, in particular Polaris, the North star, to help find their way. Though sometimes the sky could be cloudy or stormy, and they wouldn’t be able to tell which way they were heading. This is why compasses are particularly important at sea.

True North always sits at the top of the Earth. Magnetic North is not a fixed point and changes over time in response to the changes in the Earth’s core. It’s thought that it is situated around 1000 miles away in Canada. The handle, a small knurled rod above the hinge, is usually about half an inch long. Users can grip it between their pointer finger and thumb. Our STAEDTLER compasses are also available in a plastic case with a hinged lid. Depending on the model, this includes a lead box with four HB leads as well as practical accessories for school and professional use: Be inspired to do more and go further by equipping yourself with the best tools for the job. Our maps are built on 220 years of experience - we keep walkers, runners, cyclists and more safe in the great outdoors all year round. During the 12th century, Europeans created the compass rose. It enabled the creation of the eight principal winds, which includes the four cardinal directions (North, South, East, West) plus the new intercardinal directions; North-East, South-East, South-West, North-West.

Case with hinged lid containing 1 precision compass with lead part, extension bar, universal adapter and spares box The screw through the hinge holds the two legs in position. The hinge can be adjusted, depending on desired stiffness; the tighter the hinge-screw, the more accurate the compass's performance. The better quality compass, made of plated metal, is able to be finely adjusted via a small, serrated wheel usually set between the legs (see the "using a compass" animation shown above) and it has a (dangerously powerful) spring encompassing the hinge. This sort of compass is often known as a "pair of Spring-Bow Compasses". Twist the degree dial until the orienting arrow lines up with the north end of the magnetic needle. Once they're aligned, this will tell you where your direction of travel arrow is pointing. [6] X Research source Unless you always want to walk due north – follow the direction of travel arrow rather than the compass needle. The compass needle stays above the orienting arrow in or very close to the compass housing. A refrigerator magnet works well for this purpose. You can also buy plain magnets from craft stores.
