That sounds very wrong. Not a physicist, but light does not interact with magnets, or you need to get into the superconducting strength levels before it does.

It seems the optical rotation happens due to molecular structure of specific materials.
Edit, found this: https://en.wikipedia.org/wiki/Faraday_effect https://en.wikipedia.org/wiki/Faraday_effect
So a specific material plus magnetic field is needed. But still not sure how strong of a field is sufficient.
