http://www.bbc.co.uk/programmes/b0148vph The earth's outer core is a sea of molten metal. As it moves it generates our planet's magnetic field. But exactly how it does it has remained a mystery. To investigate Professor Dan Lathrop built a 3 metre model, which he'll fill with highly volatile liquid sodium...

@clintdelicious But science is BASED on experiments itself - you can either prove or disprove a theory by experimenting on it and watch where the results will lead you. I think its fundamental to perform these experiments if there is something new to discover - in this case I think they need to move on deeper into the subject. Its rediculous that they're only touching the surface of the EM field and not going any deeper to find out about these "mysteries".

I would love to know all about electromagnetism. Reading about it is mind boggling

@florencelovme There are too many scientists like this just coming up with things that seem interesting but really are inaccurate. A lot of the time its juts to get funding and money for doing elaborate, pointless experiements

@youngsmyname Bit of a lame joke really.
As a globe does nothing more than point out what the name of stuff is on the surface

@Exeunt26 Im merely stating a fact - I appreciate these programs but I think they are badly presented and very showy.

@florencelovme it's about studying these fluctuations in detail. It's not simply pulling rabbits out of hats. That's just the start.

How do you expect the magnetic field to be stable when the planets interact within the planetary system? these forces are changing constantly. Is this supposed to be a new discovery? I mean get a grip, scientists - it speaks for itself.
