Magnetic Jewelry Clasp

Many people know that the most widely used method of generating electricity is to move a conductor through a magnetic field. This is the technique used by the alternator in your car, the turbines in a hydroelectric facility, and wind generators to name a few. Even reception of broadcast signals such as FM radio is accomplished by holding a conductive antenna into the air and allowing the flux lines of a carrier wave to pass through it, inducing a signal. These sets of electromagnetic waves that are arranged in, or contain a pattern of information, can be re-configured and amplified into the signal we send to the speakers. Ironically, speakers make sound by vibrating conductors through a fluctuating magnetic field. Certainly you can understand how custom magnets would have their place in this world.

This may sound quite complicated, but in truth it is quite simple. Electromagnetic waves are all around us, and they flow from the points of emission outward filling the atmosphere with information that is eventually picked up and disregarded as noise or translated into useful information. Even the text that you are reading on your monitor right now is in some way (probably many ways) a result of electromagnetic influence. We live in a world full of magnetic fields. With some ingenuity, we can utilize magnetic materials or create electromagnets configured in particular ways to "sculpt" the fields of influence around us to assist in performing numerous tasks.

Old CRT television sets manage to guide an electron beam through the scan lines of the screen by oscillating a signal to move the beam left and right, and to drop beam a set distance down and back to the left for the next scan line. This bending of electrons is accomplished by using conductive coils to make custom magnetic fields that change in polarity and strength on demand. This is just one of the many applications of magnetic influences on our technology.

There are many devices that require magnets that are very small or very specialized, and therefore have certain attributes that make standard magnet shapes unlikely candidates. Many industries require facilities that can not only manufacture magnets to very precise specifications, but also in unique sizes and shapes. Thanks to human ingenuity, we have the ability to do just that.

In the 1980s, neodymium magnets were developed. Not only do these magnets have the ability to hold a strong charge for a long time, the process of manufacture makes them prime candidates for shaping to suit specific purposes. Custom magnets can now be made in nearly any shape or size to meet the requirements of just about any application. From gigantic generators to microscopic motors, there are magnets that are just the right size and shape to perform the task, and do it effectively and efficiently.
