They typically consist of a circular, ring-shaped [[magnet]]ic centre. The magnet is usually considered a monopole, although the central axis will have a dipole, and have the advantage of being wound continuously in a single direction, thus there is no inductive interference between windings as in a solenoid that is wound back and forth. == References == *{{Citation |last=Griffiths |first= David |year= 1989 |title= Introduction to Electrodynamics |publisher= Prentice-Hall |isbn= 0-13-481367-7 |doi=}} *{{Citation |last1=Halliday |last2= Resnick |year= 1962 |title= Physics, part two |publisher= John Wiley & Sons |isbn= |doi=}} *{{Citation |last=Hayt |first= William |year= 1989 |title= Engineering Electromagnetics |edition= 5th |publisher= McGraw-Hill |isbn= 0-07-027406-1 |doi=}} *{{Citation |last= Purcell |first= Edward M. |title= Electricity and Magnetism |edition= |year= 1965 |volume= II |series= Berkeley Physics Course |publisher= McGraw-Hill |isbn= 978-0-07-004859-1 |doi=}} *{{Citation |last1= Reitz |first1= John R. |last2= Milford |first2= Frederick J. |last3= Christy |first3= Robert W. |year= 1993 |title= Foundations of Electromagnetic Theory |publisher= Addison-Wesley |isbn= 0-201-52624-7 |doi=}} ==Other websites== * [http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/indtor.html Approximate inductance of a toroid] includes formula, but assumes circular windings [[Category:Transformers (electrical)]] [[Category:Magnetism]] {{Sci-stub}}
