electromagnetism - Can a light be bent by a magnetic field?



I'm struck with two competing ideas on the question in the title.


Listing #1:



  • How far can a magnetic field bend light?


A: Unfortunately, the path light takes is not affected by the presence of a magnetic field. Light itself is composed of an oscillating electric and magnetic field, and one very important property of electric and magnetic fields is what we call linearity. That is, if you have two sources of electric and/or magnetic fields, you can predict what the combined field is just by adding the two source fields together. The two fields don’t change each other at all.


Listing #2 (Answer #1)



  • Does electric charge affect the space time fabric? If so, why?



A: [See link. Rather, see both links if you must.]


I'm more inclined to consider the latter question and answer as the correct interpretation. Anyway, if anyone could help me out with this conceptualization that would be great, thanks.
