Is it possible to separate electric and magnetic effects in an electromagnetic phenomenon ?

Question

I would tentatively say that it depends on the phenomenon, but I'm not quite sure what you mean.  Could you elaborate?

i mean can an electric field exist without a magnetic field  and vice versa ?

anonymous · Answer

For any given observer, yes -- however, somebody moving with respect to you might see a different mix.

anonymous · Answer

how is that possible ?

I'll give you an example.  Imagine I have a metallic loop and a bar magnet.  My bar magnet will be fixed on a platform, and I will be rolling toward it with my loop on a cart.|dw:1360721069350:dw|
