L – average length of the magnetic circuit used in eq. 1 below. It is the sum of the length L core in the iron core pieces and the length L gap in the air gaps G. Both the leakage flux and the fringing fields get larger as the gaps are increased, reducing the force exerted by the magnet.
To construct the LHC magnets required more than 28 percent of the world's niobium-titanium wire production for five years, with large quantities of NbTi also used in the magnets for the LHC's huge experiment detectors. [2] Conventional fusion machines (JET, ST-40, NTSX-U and MAST) use blocks of copper. This limits their fields to 1-3 Tesla.
Neodymium is used in the electric motors of hybrid and electric automobiles [52] and in the electricity generators of some designs of commercial wind turbines (only wind turbines with "permanent magnet" generators use neodymium). [56] For example, drive electric motors of each Toyota Prius require one kilogram (2.2 pounds) of neodymium per ...
Ring magnets Most hard disk drives incorporate strong magnets This manually-powered flashlight uses a neodymium magnet to generate electricity Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the ...
When the phone is set on the pad, a coil in the pad creates a magnetic field [1] which induces a current in another coil, in the phone, charging its battery. Generic block diagram of a wireless power system. Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a ...
There are multiple setup options, too: Use the built-in rechargeable battery or connect it to existing doorbell wires. With 1080p resolution, two-way audio and lots of other useful features, this ...

Magnets are also used in other types of fastening devices, such as the magnetic base, the magnetic clamp and the refrigerator magnet. Compasses: A compass (or mariner's compass) is a magnetized pointer free to align itself with a magnetic field, most commonly Earth's magnetic field.
