Sintered Neodymium Disc Countersunk Magnet The permanent pot magnets (magnet pot or magnetic pot) position ferromagnetic items quickly and easily in the required place. these magnet systems have only one surface of magnetic attraction. In other words, all the other sides are non-magnetic. This form of construction restricts the further spread of the magnetic field. As a result, other items or machine parts in the vicinity of the pot magnet do not become magnetised.
In general, rare earth elements were given their name for two different, yet significant reasons. The first possible naming derivation relies on the initial perceived scarcity of all seventeen rare earth elements. The second suggested etymology stems from the difficult process of separating each rare earth element from its mineral ore.

The relatively small and difficult to access ore deposits containing rare earth elements contributed to the initial naming of the seventeen elements. The term “earths” simply refers to naturally occurring mineral deposits. The historical scarcity of these elements made its namesake inevitable. Currently, China meets approximately 95% of global demand for rare earths – mining and refining around 100,000 metric tons of rare earths a year. The United States, Afghanistan, Australia, and Japan also have significant rare earths reserves.
