    Two different magnets ?? :rolleyes:

    If they had said North seeking end compared to South seeking end then maybe it would be worth thinking about.

    But an effect that depends on two different magnets - nah...

    don't have a magnet on hand to test - and it's worth a test sometimes if only to say "I tried it and it didn't work"

    LCD = liquid crystals , they polarise light by aligning themselves in an alternating electicial field - I doubt magnets would affect individual cells

    magnets do affect the colours on CRT screen , until you degauss them

    and really weird magnets can rotate microwave radiation so you can use the same feed horn for send and receive because the magnets seperate the incoming and outgoing streams




    as an aside if you take a calculator apart and flip the polarid plastic the other way around you get a light on dark display looked cool but a lot harder to read, the joys of expirimenting

    The answer is obvious:

    It's MAGIC.

    But yeah I've never seen that before. I'd say if it was true, kids everywhere would be doing it.

    Any sufficiently advanced technology is indistinguishable from magic.

    in the case above it was video editing


    But many / most substances repel magnets !

    the effect is weak but it is there

    a frog is levitated using a 10 tesla magnetic coil using diamagnetism


    some day I'll get a thin slice of bismuth ( lead replacement ) and try to levitate above a magnet from an old hard drive
