Assuming what I've read is true, yes, you can get power from the earth's magnetic field, especially if you have two sattelites tethered together and rotating. However, when you do the math, this power turns out to come directly from the orbital momentum of the sattelite and will cause it to deorbit and crash. Solar panels are better power sources.
