WMF200: Magnetic Shielding Film for LF and HF Radiation (Width 4", Length 24")

I had some audio feedback from my home theater center speaker due to a tone control unit I have placed on top of it. I cut the magnetic shield to size and placed it between the two components and voila, feedback gone. It’s pricey for such a small piece of paper but it solved my problem and I’m satisfied with the results.

My IPhone’s internal magnet , which center’s it w/Apple’s surface charging system, ALSO STOPS MY BATTERY POWERED WRISTWATCHES. I tried to shield th iPhone , if I pick up my iPhone, it’s magnet i s then close enough to disrupt the watch’s operation. I spoke to Tag Heur’s customer support but they had no solution , other than Apple providing a magnet shield for when the way is NOT BEING CHARGED, and being used as it is normally !

Bought this shielding film to cover a breaker box in my living room. Managed to reduce the field from 200mG to 40mG with just one layer. Works best if you have a small area to cover, otherwise request for a larger sheet when ordering to cover a larger source.

I had some 60hz noise in my stereo introduced by my VPI ADS through an Icon Audio Step Up Transformer. I wrapped my SUT in the shield and all the interference is gone.

I had a small hum affecting my headphone amp and this shielded the power toroidal from the other transformers reducing the hum to acceptable levels.

First, I thought this was tape with adhesive. It is not. There is no adhesive so it does not stick to anything. Second, after I sprayed this plastic film with 3M 77 contact adhesive and carefully wrapped my JL Audio speaker magnets with 2 layers, they still caused my Ritchie compass to move when placed 18 inches away. If it was blocking magnetic fields, the compass should not move. Expensive and doesn't work well.

Did exactly what I needed it to do, was on time, and reasonable price

Works quite well! Exceeded my expectations.
