Current and Magnets - Sixty Symbols
Professor Roger Bowley uses fuse wire, magnets and electrical current for a quick demonstration. Visit our website at http://www.sixtysymbols.com/ We're on Facebook at http://www.facebook.com/sixt...
==========
This is two amp fuse wire it's copper, tinned copper wire which used to be used in old fashioned fuses and George has this long bit of fuse wire, which is hung between two electrodes. You probably can't see so we put some paper on this wire and you see the line across there and then it comes along here Well this is a wire which is jittering a bit because ... I don't know why .. you do just leave me ... Allright it's hanging there in a shape which doesn't seem to be particularly special. Now I am going to turn the current on This is volts going up and this is the current in amperes. So it goes all the way up and this goes up to 1.8 amps roughly, 1.75 So this is below the point where the fuse wire will melt. So now, I am going to ...
