study buddy asked:
A jumper cable used to start a stalled vehicle often carries a 15 A current. How strong is the magnetic field 11 cm away from it? What percentage of the Earth’s magnetic field (5.00 10-5 T) is this?

I’m talking about the one where he came up with the idea of using a gigantic ball of energy that rotates around the earth like a tether-ball, and then after it gains enough energy, we harness it with a big antenna, what’s that called? And I can say this with a certainty, the answer to [. Continue Reading »
