My DIY Magnetic Field Viewer (i.e. Ferro-Cell) and some interesting magnetic arrangements

I decided to film something different amongst the many different technologies I'm constantly experimenting and testing with. This isn't exclusive to Nigel Cheese but he has by far the most advanced version of this type of technology, which I explain a little of towards the end of the video. If you can handle my "uhhs" "umms" and rambling then some of the images I think are worth seeing, and are not very common anywhere on the internet. I hope you enjoy. =]
