I opened up my (now defunct) computer hard-disk and plucked out the cool 0.4 Tesla magnet - i've been having fun with it in the School Lab with the CRT (in the electron diffraction experiment) - i take the magnet close to the ZnS screen, the electrons sway - and voila! i have lovely patterns reminiscent of aurorae. Problem is, i wish to try out the above with my TV's CRT - i did it for 2 seconds and the patterns were lovely! I read that i will damage my TV if i keep the magnet close too long. Why exactly?
