The Neodymium Magnets Overview is greatly confusing to those who have not researched them. Basically, a Neodymium Magnet is a kind of permanent magnetic device that uses magnetic force to create an electric field. In this case, it is creating an electromagnetic field using Neodymium instead of iron. It is usually produced by joining the rarer, more earth-abundant neodymium elements with the more earth-abundant iron oxide elements, on the periodic table.
Many people believe that they can only find these materials at your local hardware store or even online, but in fact they are available almost everywhere and you should easily be able to find one that fits your needs. One thing to keep in mind though, if you do purchase one from the hardware store or another place like home improvement, that the Neodymium Magnets Overview will clearly state the material grade of the magnets that you purchase. If you are purchasing them online, then be sure to read all of the information in the Neodymium Magnets Overview so that you can know what grade material you are actually purchasing. You also want to make sure that the magnets you purchase are described as Nd or Yd grade. This means that they have been magnetic charged to a higher degree than most other magnets, which is required for a successful induction.
One thing to keep in mind when using these magnets is that you want to be sure that you are storing them at a high enough working temperature so that they are effective as long as they are in use. Generally speaking, you are best storing them at room temperature. However, if you must store them at a higher temperature, then the best solution is to purchase a battery operated unit. Keep in mind that the Neodymium Magnets Overview should be used as a general guide. Always double check the specifications on the product before you buy it so that you will know if it will work properly for your needs and applications.
