We have a sign warning of strong magnets in use on our mobile science vehicle.  We have strong rare earth magnets used in a magnetic sculpture style exhibit.  The sign came as a result of a physician visiting the truck and worrying that a child with a cochlear implant might lean over it and the magnet is strong enough to reset it.  First I have ever heard of that, but better safe than sorry in our case.

Does anyone indicate the presence of magnets on their exhibit floor to

visitors? We had a question about magnets from a visitor the other day

(whose child has a pacemaker) and wondered if anyone else put up signs

or had a sign at the front desk about magnets. Not MRI strength, but

evidently even refrigerator magnets can cause some problems if they

are close enough. We have a few exhibits with small tethered magnets.
