If "liquid crystals" weren't sensitive to magnetic fields then LCDs might not exist. Vsevlood Freedricksz is credited with discovering the behavior; he discovered the Freedricksz transition by applying magnetic fields to films of liquid crystals. I'd rather you explained my error than just make snide remarks about how little I must know. This is supposed to be a learning experience. When you put voltage into them, the dipoles line up, right? When dipoles align you get paramagentism, no? Liquid crystals are para-magnetic as shown by Freedricksz... Exposing an LCD to a sufficiently strong magnetic field WILL cause the crystals to migrate. Magnetic fields alter the flow of electrical charges. What happens to the transistors in an LCD when you expose them to a strong magnet while they're turned on? If you can explain why an LCD wouldn't be effected by a strong magnetic field given this I'm sure I'm not the only one who'd appreciate it.
