To increase their efficiency during energy production, these firms are also experimenting with new innovations, including...
The permanent magnet can be classified into the rare earth permanent magnet, ferrite, Al-Ni-Co based permanent magnet and other permanent magnets, but the ferrite and rare earth permanent magnet are the two major categories. The rare earth permanent materials mainly include the bonded and sintered...
An oil spill can have a devastating impact on the environment and the creatures closest to it. For years, researchers have sought to find a method to quickly and thoroughly clean up after these unfortunate spills so as to minimize the damage. The more efficiently an oil spill can be addressed, the...
The neodymium magnets we sell are extremely strong, and must be handled with care to avoid personal injury and damage to the magnets. Fingers and other body parts can get severely pinched between two attracting magnets. Neodymium magnets are brittle, and can peel, crack or shatter if allowed to...
Klaus HalbachThe Halbach array is named for its inventor Klaus Halbach, a Berkley Labs physicist in the engineering division. The array was originally designed to help focus the beams in particle accelerators. In the picture on the left, Klaus Halbach in 1986 with Kwan-Je Kim discussing a model of...
The pictures above show the lopsided shape of the array's magnetic field using Magnetic Viewing Film. Notice how the field appears to be open on the left, and closed on the right? That is your first indication of what a halbach array actually is. The array is nothing more than 5 identical magnets...
It depends on the application. If you need the highest strength in the smallest possible package at room temperature, grade N52 is the strongest available.
