Gee, why not?

...but I guess electric fields don't affect light either.
Hey!
Light propagation is characterized by alternating electric and magnetic fields ...or something like that, right?
Electric and magnetic components are perpendicular to each other, with sine wave ...nature.
Are the electric and magnetic peaks in phase with each other?
Yes, of course they are (well I'll assume....)
So my problem is that I picture a field as 3 dimensional, say like a doughnut or....
...but then why doesn't it overlap with the magnetic 3-D field...?
I guess I need to learn more about what polarization detects....
...the orientation of the fields, not the fields themselves....
hmmmm. Any comments, thoughts, guidance, suggestions, opinions, etc.?
...but then why don't other magnetic fields affect light? Is is just one dimension of a magnetic field that is being propagated, or a whole 3-D field?
