There's no such thing as a room temperature super-conducting magnet. You are talking about "high temperature" magnets, which are YBCO tape magnets. High temperature, in this case, means about -290 degrees F.

The next breakthrough that will come will be YBCO powder-in-tube wires, that will allow much stronger fields than currently. They'll be here within a decade, probably much less, as working prototypes exist now.
