Since the Earth has a magnetic field, can it, in theory, be run through a conductive metal coil to create electricity?
I need to shield my device from magnetic interference, including earth magnetic field (if you move device around, it might be enough to cause slight currents i guess) and magnetic field caused by ...
What is the reason for the Earth to behave like a bar magnet and have poles (North and South poles)?
The Earth rotates about it's own axis. Do the geomagnetic field lines rotate due to this rotation or not?
Does the Earth magnetic pole point to something in our solar system or farther? Like the Sun.
Is it true that on average, people who grow up in a geographical location of the earth where the magnetic field strength is stronger than other geographical locations, develop more to their genetic ...
