What if your toroid transformer is super conducting?
« on: October 15, 2019, 08:57:03 pm »
Say you were wrapping a toroid and you put it in liquid nitrogen would the value (henry's) go way up or down? What if the toroid was made from YBCO material, or what if the ring was made from a type I superconductor (the ones where liquid helium is needed)? The same value? Would this have any practical application?

YBCO could be crushed into toroids as its like a ceramic and works at liquid nitrogen temps.

The purpose of a laminated core, either EI or toroidal is to prevent eddy current losses. A laminated superconducting core would behave identically (material characteristics permitting).

A solid superconducting core would increase your core losses to infinity - zero inductance.
