Is it possible to harness magnetic energy for electricity?

Most of the magnetic fields we deal with, we spend energy to create in the first place, so they are not a power source. The exception is using the Earth's magnetic field, but even then, we are converting kinetic energy into electrical by using electromagnetic induction. read more
