... We can visualize the Earth’s magnetic field as being produced by a giant bar magnet within the Earth. What we call the “North geographic pole” corresponds to the “south pole” of the imaginary bar magnetic so that the north needle on a compass points towards the north geographic pole! ...

Magnetic Effects due to Electric Currents Result:
... The direction of the induced current (generated by changing magnetic flux) is such that it produces a magnetic field that opposes the change in original flux. E.g. If field increases with time the field produced by induced current will be opposite in direction to original external field (and vice ...
