Types of Temperature Losses of Magnets (= loss of magnetisation due to high temperature) Depending on the temperature, we distinguish between three different types of losses: Reversible temperature loss Temperature area: just above the maximum working temperature The magnet is less magnetic as long as it is hot. Once it is cooled down, it regains [...]
Useful facts about permanent magnets The proportioning of permanent magnets, that is the ratio of the magnet pole areas to the magnet thickness (L/D-ratio) of any magnet material, is subject to the laws of physics. The maximum operating temperature also depends on the L/D-ratio. A thin NeoDelta magnet disc of 15 ø x 2 mm [...]
Magnetic Monopoles: Their Construction and Use Magnetic monopoles, objects bearing a magnetic charge without an corresponding opposite charge, has been postulated by established science, but so far never observed. In this short paper I will demonstrate how to build macroscopic monopoles, and how they can be employed for various purposes. Some applications to ether storage [...]
Choosing the right ferrite cores to increase the efficiency of your product Capacitors are often used as noise suppression components. But they are not always the optimal solution because they discharge the noise to the ground. Ferrite cores, however, can suppress noise without grounding. By Baishakhi Dutta Ferrites have the ability to attract magnetic flux. [...]
Neodymium Iron Boron Temperature - Temperature Effects on Neodymium Iron Boron (NdFeB magnets) Temperature characteristics of NdFeB grades: The NdFeB magnets are the strongest magnets available. Up to +150 degrees C, they are stronger than the other Rare Earth magnet, SmCo. At around +150 degrees C and above these Neo magnets perform not as strongly [...]
It is possible to demagnetise a Neodymium magnet by applying an external magnetic field in a direction opposite to the direction of magnetisation (DoM) of the NdFeB magnet. The extent of demagnetisation is a function of the total magnetic circuit (and hence the Intrinsic working point), the temperature (and hence the actual BH curve shape [...]
