She might be creating a magnetic filed but it will only be one of a very,
very, very, limited range just like the ones generated on Earth. It is not
going to harm anyone in the hospital unless they are lying inside the MRI
scanner let alone anyone on Earth.

Actually, if you've used an MRI, you'll know that if you stand next to
it but still outside of it, wearing some sort of ferrous-metal, maybe
in your watch, the it will be attracted to the MRI. The field is not
just inside the MRI but also passes outside of it. It's just then the
field is only uniform inside the MRI. (it's an example of a Solenoid)

Will it fry your brain. Will it fry the brain of anyone inside the machine. No.


Where are these alien devices? How come there were no sconces showing them

Because besides having to show a story, Doctor Who also needs to be a
certain length so it can't spend 20 minutes explaining how a device
works or showing someone setting up their plan, as much as we'd like

Well it could have had the 20 minutes it needed by cutting out all the soap. And in any case the idea RTD came up was total and utter unscientific garbage and he should have been forced to re-write his script and come up with a better idea, like the one I suggested in my re-write, which would not have require any detailed explanation.

that. They also are limited in money so rather than use a lot more of
the FX budget and the props budget, sometimes an action will have to
be described. It would be nice if they could show all of those scenes
but it's not realistic to expect it. Ron Moore, of Battlestar
Galactica, often complains about that on his podcasts, that sometimes,
even as much as he'd like to, he can't show everything and sometimes
just has to describe it for the sake of time and money.

What we need to know is how this magnetic filed is going to reach the Earth.
Right now its totally contained in the MRI scanner and not sufficiently
powerful enough to do any harm to anyone unless they are positioned very
close to it.

It really isn't contained in the MRI scanner, the field goes outside
of the MRI itself.

The MRI scanner has shielding and probably has focusing devices like the pieces of metal you put on the end of magnets to concentrate the field in one area.

Because its been done already.

Really? What is the exact explanation of how the TARDIS travels in
time or how it makes a forcefield? And be specific.

It travels in the Space-Time vortex and it makes its forcefield using one of those whatsit surfboard extrapolator things that the Doctor and Captain Jack pluged into it.

In which case there must be scientific explanations of how things work and
why they are going to harm people, because the ordinary members for the
audience who have passed their GCSE in magnetism and even those who have not
know perfectly well the when picking up something up a magnet and then
moving it away the force drops off very quickly. It is a short range force
so how is a 50 kT field generated inside a magnetically shielded MRI scanner
in a very tiny space going to reach the Earth at sufficient intensity to
kill people? And what the hell is it being powered by anyway?

With a very powerful, large field, which she is trying to make, the
waves will propagate to Earth. I have already answered how it is
powered.

POPPY***. The magnetic field strength will dissipate to almost nothing within meters of the machine even if guides were used to try to focus it (which would have to be strung all the way through space in the direction of the Earth). There is nothing that is powerful enough which can produce a sufficiently strong enough filed that would have a strength of 50 kT at the distance of the Earth from the moon except a super nova (and even that is questionable, but at least you get a gamma ray burst which will do the job of killing everyone).

In the words of Jesus Christ, seeing as its Good Friday. It is you that say
that.

You didn't say that specifically, but all of those people have
described Science Fiction as I did so to you and you described that as
being "CARP." So, either you know better than all of those people or
you're wrong.

No. What is the genre called "Science Fiction" or "Lets not mention and science Fiction"?
