A local affiliate of CBS reports:
General Atomics is scheduled on Friday to unveil a 1,000-ton superconducting electromagnet to be used in a 35-nation fusion energy study. According to General Atomics, the Poway-built device that's powerful enough to lift an aircraft carrier out of the water will be showcased at a news conference in Poway.
The electromagnet will be used in the International Thermonuclear Experimental Reactor experiments in France, in which scientists will try to create a burning plasma that demonstrates the feasibility of fusion energy. Clean fusion energy has been a holy grail for researchers looking for alternatives to standard nuclear energy and carbon-based fuels. Scientists say fusion energy does not create long-term waste products or meltdown risks.
General Atomics is more well-known for their Predator and Reaper military drones. As much negativity is swirling around these parts about the military industrial complex, there could be much potential benefit from the technological progress General Atomics and others are making. What do you all think?

So what you say is that this electromagnet is powerful enough to accomplish net power output from a fusion process?
Perhaps even net economic output too?

donno but "worlds most powerful" would imply that if the output varies by the second power of magnet strength then its 4 times more output that something half the strength all other things being equal.
The space shuttle's main engines had the highest shipping / used Isp characteristic of any shipping/operating engine at one time (maybe still holds record, don't know) although thats very helpful for a Hubble telescope repair mission its not the only requirement for overall mission success.

So this electromagnet will put the nuclear process above the threshold of net power output?
Many fusion processes seems to be dependent on reaction size big large enough.

Well, plasmas are not very friendly, it turns out that having too high of a magnetic field will also lead to instability. So the answer is, it depends.
