hey ther, just a quick question. my monitor at work has a little black bok clipped on to it, and inside this box is two magnets which come together to encircle the cable. does anyone know what this is for?
not a very interesting question i know, but it drives me crazy not knowing things once i start thinking about them.
thanks people. :)
 
That box is known as a ferric bead. There are two ferric (magnet materials) cores in the box that encircles the cable. This is to filter out interference and distortions in the signal of the cable. This is also known as a choke.
 
thanks for that, i feel much better lol. hate not knowing things, really bugs me lol
thanks again. :)
later skater
 
Is is my pc or is there something wrong with his post count?
 
True. True.

I guess reason why I take noticed of them more is because you have to manually place them on the cable.
