The field of a magnet is the sum of fields from all magnetized volume elements, which consist of small magnetic dipoles on an atomic level. The direct summation of all those dipole fields requires three-dimensional integration to obtain the field of one magnet, which may be intricate.
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism.
BTDigg was founded by Nina Evseenko in January 2011. The site is also available via the I2P network and Tor.In March–April 2011, several new features were introduced, among them web plugin to search with one click, qBittorrent plugin, showing torrent info-hash as QR code picture, torrent fakes and duplicates detection, and charts of the popular torrents in soft real-time.
A permanent magnet in such a field rotates so as to maintain its alignment with the external field. Magnetic torque is used to drive electric motors. In one simple motor design, a magnet is fixed to a freely rotating shaft and subjected to a magnetic field from an array of electromagnets. By continuously switching the electric current through ...

The screw and magnet spin, with the screw tip acting as a bearing. A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field.
An intermediate ferromagnetic pole "stator" is usually held stationary between the rings, to direct the concentration of the magnetic lines between the high speed rotor and the low speed rotor. The gear ratio between the rotors is the number of magnetic pole pairs on the high speed rotor to the number of magnetic pole pairs on the low speed rotor.
