Ok, this is going to sound strange but stick with me for a moment. I need to put some sort of magnetic shied up around my TV so that I don't screw it up. I am not sure of the source of the magnetic ...

Low-frequency magnetic fields can impact electronic devices, inducing unwanted current flows in sensitive paths that can add noise, introduce errors, and otherwise disrupt carefully balanced circuits.

The idea of shielding spacecraft from harmful cosmic radiation using artificially-generated magnetic fields was once dismissed as unrealistically expensive. But new experiments carried out in the UK ...
