Were you thinking 100 MJ perhaps (which seems awfully low). Energy isn't normally measured in tons. But if you were applying e = mc^2, then that would be 8.98

Were you thinking 100 MJ perhaps (which seems awfully low). Energy isn't normally measured in tons. But if you were applying e = mc^2, then that would be 8.988e21 MJ [1], which is a considerable amount of energy.

- pfdietz 7y agoThe energy stored in the part of the Earth's magnetic field above the surface is about the same as the yield of a 100 megaton nuclear bomb. This is about 4e17 J, or about 13 gigawatt-years. Mars is smaller, and so the volume of the magnetic field would be smaller, and a lower field is probably enough. Since stored energy goes as B^2, maybe this energy could be reduced by two orders of magnitude.
