Someone is asking me how much current in a loop of wire the diameter of the earth to make the same level of magnetism the earth has?
I hope I am asking this correctly.

It turns out I did more than round off, I made a power-of-10 error in the resistance. That made the needed Voltage too high by a factor of 10....I'll be rounding off values here.
The updated values would be 945,000 GW and generating capacity short by a factor of 60.Clearly, we now need a power calculation.
6.3E13 volts X 150 amps = 9.45E15 watts = 9,450,000 GW.
Total world electrical generating capacity = 15,856 GW (https://www.cia.gov/library/publications/the-world-factbook/rankorder/2236rank.html)
The total world generating capacity is only short by a factor of 600.
