Editing Levitated Dipole Experiment (section)

=== Dipole ===
This experiment needed a special free-floating electromagnet, which created the unique "toilet-bowl" magnetic field. 
The magnetic field was originally made of three coils. 
Each coil contained a 19-strand [[niobium-tin]] [[Rutherford cable]] (common in low-temperature superconducting magnets). 
These looped around inside an [[inconel]] structure; creating a magnet that looked like an oversized donut. 
The donut was charged using [[Electromagnetic induction|induction]]. 
Once charged, it generated a magnetic field for roughly an 8-hour period. Overall, the ring weighed 560 kilograms<ref name="Garnier2006">{{cite journal|last1=Garnier|first1=D.T.|last2=Hansen|first2=A.K.|last3=Mauel|first3=M.E.|last4=Michael|first4=P.C.|last5=Minervini|first5=J.V.|last6=Radovinsky|first6=A.|last7=Zhukovsky|first7=A.|last8=Boxer|first8=A.|last9=Ellsworth|first9=J.L.|last10=Karim|first10=I.|last11=Ortiz|first11=E.E.|year=2006|title=Design and initial operation of the LDX facility|journal=[[Fusion Engineering and Design]]|volume=81|issue=20–22|pages=2371–2380|doi=10.1016/j.fusengdes.2006.07.002|bibcode=2006FusED..81.2371G }}</ref> and levitated 1.6 meters above a superconducting ring.<ref>{{cite web|title=The Levitated Dipole Experiment|url=https://www-internal.psfc.mit.edu/ldx/ldx.html#1.1%20Levitated%20Ring|publisher=MIT|access-date=7 August 2016}}</ref> 
The ring produced a 5.7 T peak field.<ref name = "Construction">"Design and Fabrication of the Cryostat for the Floating Coil of the Levitated Dipole Experiment (LDX)" A. Zhukovsky, M. Morgan, D. Garnier, A. Radovinsky, B. Smith, J. Schultz, L. Myatt, S. Pourrahimi, J. Minervini.</ref> 
This superconductor was encased inside a liquid helium cryostat, which kept the electromagnet below 10 [[kelvin]]s.<ref name = "Construction"/>
