Magnetic field redirection?
I'm working on a project that I will post an 'ible of, (truly wireless speakers ;)) but I need some method of redirecting a magnetic field so it doesn't interfere with the speakers. I have heard of some methods, i.e. Mu metals, MagnetShield, but these are not easy to come by, especially in the UK. I have considered ordering from the manufacturer, but I am not willing to pay the exorbitant shipping costs.
I would firstly like to know if such a material exists, or if alternative/better/cheaper methods are available, secondly, whether or not it can be procured in the UK, and if so, where, and thirdly, proper application of such a material.
I have done lots of research into the matter, but have been left fruitless. I'm sure someone can help.
