NdFeB magnets, being the strongest known permanent magnets, are warned to
be
a hazard to people with pacemakers. I would expect a magnet could disrupt
a
device that uses magnetic or certain static fields for operation, such as
computer hard drives, magnetic recording media, CRT screens, etc. It can
also mechanically damage some things, like bending the fragile mask inside
a CRT tube.
But I have found no effect of such a magnet on an electric circuit.
So my question, what is in a pacemaker that would make it susceptible to a
strong magnetic field like this?
Yeah, this is probably more of a biomedical engineering question than just
an electrical engineering question. But sci.engr.biomed seems to be dead
(not counting spam).
