Keeper for Earth magnetism

Seeing all iron magnets lose their magnetism over time*, I propose the planet Earth needs a keeper.

It's less tricky than you think. All it needs a base station at each pole and very long bit of iron. See image in link.

The very long bit of iron could be, say 35,000 feet up, so giving long-haul planes somewhere to perch, eat some bird seed and it's put its cockpit under its wing to get 40 winks.

*maybe

       The Earh?   

       Alas, though, I'm not convinced this is needed. The Earh's magnetic field is supposedly generated by convection in the iron-nickel core. It's all a bit arm-wavey, but the basic argument is that the flow, in the presence of a magnetic field, generates a current which in turn generates the magnetic field, in a sort of pulling-yourself-up -by-your- bootlaces manner.   

       However, it is interesting to ponder what would happen if you provided an additional path for the magnetism. I can confidently say that I have no idea of the answer.   

       On reflection, though, I think there's a fair chance that it would work like some sort of homopolar motor, and the iron band would begin to circle the earth at ever-increasing speeds.

       ...or a way to extract energy from earth's magnetic field. How much could we get anyway?

       Loads .... shhhh, and we'll let you have some (until the poles flip, which will be sooner now).
