Distance gets in on the act too. Far field in normally taken as 20 lambda from a source. Within that area, as you get nearer the source, you can find predominantly one field more than the other. Another factor is skin depth and then there is the permeability of the shield.

However, use of the prefix - Faraday takes care of all that and specifies a shield designed to pass magnetic components. And as we all learn in trying to screen things, electric components aren't too bad, it's the magnetic ones which are the devils.
