Re: [CAD_CAM_EDM_DRO] help putting together a complete system

What did it feel like having the MRI? I remember seeing on Tommorow's World
when they first came out one of the presenters held a piece of motor bike
lock chain a few feet away and they turned the scanner on. The chain
instantly pulled taught towards the scanner, I wonder how angry they'd be if
she'd let go by mistake? :-) They were saying about how they plan to do
surgery inside the scanner so they can see inside the person as they operate
but they'd all have to use plastic knives and things from the chippy so they
didn't stick to the scanner. I can imagine it now, 'I'll take three scapels,
five sets of hold clamps and erm... give me a few portions of chips while
your at it please.' I wonder if there is actually a measurable current
induced in the iron compounds in your blood as you are scanned. You are
moving through the field and it sure is one big field. I wonder what gauss
(Sp?) they are? I have also always wondered why we say a transformer is
almost 100% efficient but 50% of each coil is facing the wrong way, i.e.
backwards to the opposite coil.
