In physics‚ the term solenoid refers to a long‚ thin loop of wire‚ often wrapped around a metallic core‚ which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets. The term solenoid refers specifically to a magnet designed to produce a uniform magnetic field in a volume of space (where some experiment might be carried out). In engineering‚ the term solenoid may also refer

understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor (the part that rotates) containing several coils of wire. This is attached to the output shaft. The rotor is surrounded by a magnetic field (this is usually a permanent magnet‚ but can be an electro magnet). Electrical connection to the rotor is accomplished via a device called a commutator. A commutator is basically a conductive ring that rotates with the rotor shaft. This ring

and bigger an issue. Therefore‚ it is only natural that demands for it are growing rapidly. To meet this demand‚ yet another form of transportation has been introduced: the Maglev train. Maglev‚ derived from the term magnetic levitation‚ is a method of propulsion that uses magnetic levitation to propel vehicles with electromagnets rather than with wheels‚ which causes friction and can wear out the rails. With maglev‚ a vehicle is levitated a short distance away from a guide way using magnets to create

The magnetic confinement of the plasma particles in the vacuum vessel torus is obtained through the combination of toroidal and poloidal fields produced by external coils (see fig.I.1) with the additional field produced by the electrical current flowing along the
