Strong magnets and handling of same

%20580/20170322_104555.jpg Just received a bunch of strong magnets supposedly for fixing the sliding curtain/door. Wrong part as it happens, but anyway. They came all stuck together in an ungainly clump (not in a nice package as they usually do) and were a real ******* to slide apart because the washers and the plastic bags had become entangled. Photo as a reminder of what happens if your grip slips just after you have slid two strong magnets apart. Obviously going to be one of those days.

I was playing with one, and one of their staff told me to be careful. A few months before, someone had put one in each trouser pocket, at which point they smashed together very hard, and he had to be rushed to hospital in agony. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

They then pull together inside and shut of circulation to the tissues that are in between. Robert |

"Tim Streater" wrote in message
.. . Once at CERN I had the chance to be inside a large electro-magnet with the power on. About the size of a small room inside, it used 2MW DC. You had to remove anything with metal in it - watch, belt, etc. Powered up, it was then interesting to do things like take a solid alloy cylinder about the size of a tin of baked beans, and support one side of the bottom with a finger, and watch it rotate as if in almost zero gravity. Once off your finger it then fell in the normal way. If it had been AC that powered the magnet, you'd get induced eddy currents and the "tin can" would glow red hot - now that would have been impressive. I'd be no good in an AC magnet of that size because I had a metal stent fitted in one of my heart arteries after a heart attack. A DC magnet would be fine as long as the current was increased slowly rather than instant-on, because stents are non-magnetic. Likewise presumably for metal hip joints. |

PS: I haven't seen "same" (in the thread title) used as a pronoun, where I'd have used "them", since I was a lad and went to the pantomime at the City Varieties in Leeds. The programme said "if any lady patrons are wearing large hats, will they kindly remove same" which I thought looked archaic - like "all tickets must be shewn" (instead of "shown").- even in the 1960s, never mind the 2010s. |

Photo as a reminder of what happens if your grip slips just after you have slid two strong magnets apart. Obviously going to be one of those days. T work we had some 'pancake' motors about 4" dia. The magnets were about 3"x?" and f'ing strong. I went to put one on the side of a filing cabinet and got little pinches on thumb and 2 fingers, fortunately not blood blisters. The magnet had to be slid off as it was too thin to lift off. An interesting thing to do is to drop a one down the inside of a copper tube. (I leave it as an exercise to the reader to work out what will happen.) Electrifying? I'm guessing it will drop very slowly. Once at CERN I had the chance to be inside a large electro-magnet with the power on. About the size of a small room inside, it used 2MW DC. You had to remove anything with metal in it - watch, belt, etc. Powered up, it was then interesting to do things like take a solid ally cylinder about the size of a tin of baked beans, and support one side of the bottom with a finger, and watch it rotate as if in almost zero gravity. Once off your finger it then fell in the normal way. ICBA to search Youtube, but there are videos out there showing lumps of copper being dropped down the axis of a hollow vertical strong electromagnet, and falling very slowly because of eddy current "braking". Or more closely related, the other way around - strong magnet down copper tube. Has to be a strong one mind... -- Jim K |
