Magnetism and the iron in your blood !!
« on: 20/06/2006 23:09:50 »
Dearest Magnet Knowing Peeps,

Is it possible for a magnet to be so strong that it could disrupt the iron in your blood ?...what would be the resultant effect of making all the iron cling to the sides of your veins ?

In fact...when people have those MRI scans...does it affect the iron in the blood ?

My wifey must have a problem to do with this, as she's always going on about there being too much ironing !! :D...(oh...gawwwd !!!..that is so bad...I promise better quips when I've had some zzzzzzzzzzzzzzzzzzzzzz's)

Men are the same as women, just inside out !

I dont know much about magnetism, but I believe that Iron is magnetic.

for those of you who have seen the movie x-men 2, Magneto escapes his plastic prison by stealing the iron out of the poor security guards body and using it as a magnetic weapon.  Maybe this will teach you a lesson to not make the magnet too powerful, at risk of an ironic death :D:D

E=MC2... m=deg/360 X C... C= PiD

therefore E=deg/360 X 2(PiD)

no science guy magneto does not steal the iron from the security guys body but rather rips out the ferrofluid mystique injected into the security guard the previous night.

J.B.S Haldane on the perforated eardrums which were a consequence of his pressure experiments "the drum generally heals up; and if a hole remains in it, although one is somewhat deaf, one can blow tobacco smoke out of  the ear in question, which is a social accomplishment".

" In MRI the changes in blood oxygenation level are visible. Oxyhaemoglobin (the principal haemoglobin in arterial blood) has no substantial magnetic properties, but deoxyhaemoglobin (present in the draining veins after the oxygen has been unloaded in the tissues) is strongly paramagnetic. It can thus serve as an intrinsic paramagnetic contrast agent in appropriately performed brain MRI."

Thanks guys....so...do you think a strong enough magnetic field could do a human harm ?....turn us all into human compasses !! ?

The strong magnetic field in a MRI scanner,(1000x earth's), could affect neurological (electrical) function:-

" Depressed get a lift from MRI
Brain scanners please manic-depressives
By William J. Cromie
Harvard News Office


Both the patients and psychiatrists were startled. Manic-depressives undergoing brain scans, not a really pleasant experience, came out of the machine happier than when they went in.

One severely depressed woman left the scanner laughing and joking. It was totally not like her. After a 20-minute scan, another woman happily asked a researcher, "What did you do to me?"

Aimee Parow, the researcher, told Perry Renshaw, director of the Brain Imaging Center at McLean Hospital, a psychiatric affiliate of Harvard Medical School, where the scanning was done. The research team was trying to determine how the brain chemistry of manic-depressives differs from that of people who are free of the problem. Nobody expected to find such a happy result. "It was amazing," Renshaw comments.

He described what happened to Bruce Cohen, president and chief psychiatrist at McLean. "I was excited but skeptical," he recalls. "One part of me said, 'It's unlikely.' But another part said, 'Why not?' People go in and out of depression on their own. Electromagnetic fields generated by the scanner could nudge a depressed brain back toward normal." "

Robert..

I really wish you'd put more effort into suppying information..;)

THANK YOU...that's astonishing !!
