Measuring Magnetism

Magnetism is a very interesting topic. Playing with magnets can be a very fun and interesting thing to do. It is easy to feel a magnetic force when magnets are close together. They are very fun and interesting, but what makes magnets work?

Magnetic fields are generated by microscopic rotating electrical charges, according to HyperPhysics. All electrical charges have a specific set of angular motions or spins. The little charges spin very, very fast. When electrons form a pair, they will most likely have one side spin up, (which is the direction they spin) and the other spin down. This is likely to happen in most of them, but sometimes …show more content…

These are usually the two places that magnetism is the most powerful. These poles are called the north seeking poles and south seeking poles. When you put two alike poles together, for example, two north seeking poles, they will fight and repel against each other. When you put a south and north seeking pole together with a south seeking pole, they are attracted to one another and stick together. The attracting, or repelling of magnets, depends on how close they are. They also depend on how strong their magnetic fields are. The further apart magnets are the less attracted they are to each other, The same goes for how much they are attracted to each other. Magnetic force strength depends on how big and how far apart magnets are. When a magnet is broken into little tiny pieces, a north pole will appear at one end of it along with a south pole. No matter how small or big the pieces are, they will still all end up having a north pole, and a south pole. The larger a magnet is, the stronger it becomes. Also the closer it is to an object the stronger it will become. This is how most normal magnets behave(“Website,” …show more content…

A long tail like you would see on a comet. Near Earth, however, the lines stay very close to the “dipole pattern” of a bar magnet, that named because of its two poles. To Faraday, field lines were mostly a way of showing the structure of the magnetic force. In space research though, they have a much bigger significance, because electrons and ions tend to stay attached to them, like beads on a string, even becoming trapped when conditions are right. Because of this attachment, they define an “easy direction” in the rarefied gas of space, like the grain in a piece of wood, a direction in which ions and electrons, as well as electric currents can easily move. In contrast, motion from one line to another is harder. A map of the magnetic field lines of the magnetosphere tells, at first look, how different regions are linked and many other important properties. Faraday not only viewed the space around a magnet as filled with field lines, but also developed an intuitive notion that such space was itself modified, even if it was a complete vacuum. His younger contemporary, a Scottish physicist named James Clerk Maxwell placed this notion on a firm mathematical footing, including in it electrical forces as well as magnetic ones. A modified area like this is now known as an electromagnetic field. Today electromagnetic fields are a very
