A toroid is a doughnut-shaped object whose surface is a torus. Its annular shape is generated by revolving a circle around an axis external to the circle. A coil of insulated wire in a doughnut shape (usually with a core of iron or similar metal) is an example of a toroidal object. These are used as inductors in circuits such as low frequency transmitters and receivers because they possess higher inductance and carry greater current than similarly constructed solenoids. They are also used as transformers in main power supplies. Toroidal coils reduce electrical resistance, due to the larger diameter and smaller number of windings. The magnetic flux in a toroid is confined to the core, preventing its energy from being absorbed by nearby objects. ==See also== * Electronics * Magnetic core * Tesla coil
How many surfaces does a toroid have? One or two? What about extensions to additional spatial dimensions? Does it make sense to talk about the number of surfaces of a 4D toroid? Wgat would a "Mobius toroid" be like? User:Memenen 14:30, 20 Mar 2005 (UTC)
