Would non magnetic matters be affected by magnetism?

[alchemist]

would non magnetic matters be affected by magnetism? and why? and why do the Earth have a natural magnetic field??

 

[Chen]

I think the Earth's magnetic field is generated by its spin around its axis...

 

[Matt Jacques]

The Earth's magnetic field is caused by rotation and more specifically the churning of the Earth's molten iron core.

Why is that? Well, I'm not totally sure but I believe the churning molten core causes currents to be induced and currents cause electromagnetism?

Yes, normally non-magnetic things are not affected by magnetism. However, if you put an enormous magnetic field through something, say a spider, a cherry or anything it will be affected. In fact, I saw on the Discovery channel a facility in Japan was able to levitate a spider with extreme amounts of electromagnetism.

I have learned in my short science career that when it comes to electromagnetism, this explanation will make you sound smart even when you don't have a clue what you're talking about.

How rude! That's why I said I am not sure and ended my sentence with a question mark! I'm eager to hear your explanation from your distinguished science career.

This is an ongoing topic of research for geologists. There was a Topic in Earth Sciences about the research being done, mostly the work of http://complex.umd.edu/dynamo/index.html , who is trying to reproduce the effect in the lab. So far, no-one has been able to succesfully recreate a self-generating magnetic field from an homogenous dynamo. So the rotating of the core and convection currents in the mantle are probably generating the field, but until we can make it happen in the lab, we can't really say for certain that it's possible.
