As the vast majority of organic materials and molecules mylar is diamagnetic. It was the substrate of choice for magnetic tapes and is often use as substrates in a wild range of experiments / measurements involving electrical optical and magnetic phenomena. Tough it can be commercially come layered with metal, as Aluminum for instance. I do not know how much the paramagnetismus of it can interfere in your case. Just take bare mylar.
