    When you drop a magnet into a copper pipe, it does something very strange...

    My friend Al at the Music Shop in Park Rapids MN showed me the magnet in a copper pipe trick. He likes to show that to kids that wonder in, they get a kick out if it.
    He learned it in science class in the 60s. I had science class in the 70s and we got as far as vinegar and baking soda, we played with mercury, licked lead and breathed asbestos.

    I remember in elementary school (late fifties) when someone brought some mercury to class, and the teacher let us pass it, in our hands, from student to student, to see how unique it was.
    Flash forward to the 1990's-2000's, when I was a neon glassblower, (we used mercury in neon production) and we had to be tested for mercury levels on a yearly basis......and occasionally neon shops got shut down by OSHA for excessive mercury contamination.

    It's also a way to sort pre-1982 95% copper pennies from the current ~97% zinc with copper plating pennies

    We did the same in our Grade 10 physics class in 1964-65.

    We did this as well in '64 or '65.

    I love this science , they (scientists ) have created metalic glass once the application is understood ....welcome to future technologies



    We live in interesting times ! I envy the young , cool stuff ahead for you !

    Blimey - I never knew that! No wonder my education was stunted - the only practical science class demonstration of anything I can remember is the behaviour of iron filings on a piece of paper above a magnet.
    Get to it, Bad Dog pickup design boffins! :)

    I remember in Vo-tech we used to put a charge on one of these and put it in someone's coat pocket or just say "here catch" and throw it at them..

    always got a charge out of that..:D

    That's so cool, never seen that before.
    I will have to try magnet/copper tricks with the grandkids:cool:

    I remember playing with mercury as a kid. We probably did plenty things never giving a thought to dangero_O

    Like copper, aluminum is also paramagnetic (magnets won't stick; the metal reacts only to a moving magnetic field).

    Tip an aluminim baking sheet at a steep angle and allow a magnet to slide down. It hits the brakes and moves slowly.

    Paramagnetism also acts to heat the metal, similarly to how a microwave works (molecular friction). Check this out:

    About 84-85 I worked at a tune up joint in Dallas. My only "formal" automotive schooling was high school shop class. Nobody there was smart enough to know a condenser was a capacitor that would hold a charge.
    I learnt all about it my first day on the job!

    To this day on those rare occasions when I change out points and condensers. I still pull them from the box carefully and touch the lead to the case. :rolleyes:
