Magnetic Flux I enjoy experimenting with magnets. I have this old color C.R.T. television setting on a shelf that I use to see how strong my magnets are. Also shown on www.myelectronicart.com Weak magnets produce 2 or 3 lines of force, fairly strong magnets produce about 7 lines of force, very strong magnets produce 20 or 30 lines of force. When I am done, if I wanted to watch TV, I would have to degauss it.
