magnetic clip on a necklace

I just received an expensive 18" bronze necklace as a gift that has a magnetic clasp rather than the traditional lobster claw clasp. The magnetic clasp is small but has enough power to hold a weighty necklace together. If the necklace travels so that the clasp migrates to the front, it will probably be about 3" away from my pacer. I have never worn such clasps since I had my pacer implanted 8 years ago. I did a search of old posts and did not find anything to give me and information. Has anyone had any experience? Is this something I need to return or is it safe to wear?

Let's talk magnets

That magnet is a rare earth super magnet. Extremely strong for its size. You ask is it safe for you to wear?

Yes, No, Maybe. Let's look at it realistically.

When that magnet is attached to its other half, the magnetic flux & its field are MOSTLY captured by the keeper & there is very little leakage. Take that keeper off, & it's Katy Bar the Door! Big time.

Have you worn it yet? Did it affect your PM? I'm guessing that it did not.

If all you have is a PM, the magnet will not permanently affect its operation at all, should it get near enough to affect it at all. They use a magnet to download your PM in the Dr's office & that doesn't permanently affect you, does it?

Here's what you can do & it's perfectly safe. Hook the magnet to its keeper & hold it in your fist (The fist will NOT affect any magnetic field, it's just convenient) Sloooooowly move your fist nearer to the PM, see if it gives you the same feeling you get when they download the PM. If not, keep bringing it closer till it's about as close as it can get to your PM while around your neck. If it does affect you, STOP & put the necklace away till you can take it to a jeweler & get a lobster claw put on it.

If it passed that test, Now place it around your neck, magnet connected to the keeper & slowly move it around your neck till it's as close as it can get. . No funny feeling, you are home free. Funny feeling, get it away from the PM as fast as you can & don't wear it.

I just happened to think - my Wife has one of those & she cannot manipulate it behind her neck, so I get the magnetic clasp fastening duties. Her nape is about even w/ my M & I've never felt any affect from it, either assembled or separated.

I really think you are safe, but you should try this out for safety sake.

Here's the real scoop on magnetic clasps...

...these are two comments I posted in the past year. See if they help. I've since used a strong rare earth magnet on the back of a nametag to test my PM & it had zero effect on it.

Thanks for the reminder

I've been meaning to do this since trhe last time the question was asked.

I found my wife's necklace w/ the magnetic clutch on it & ran it up & down my chest & around my neck. NO EFFECT.

Then I found a little plastic tube w/ three of them in it & did the same thing. Again, no effect.

I think I can safely say you SHOULD be OK.

Worrying about it can be just as bad as having something happen, so if you cannot accept my test & your apparent lack of effect, get rid of the clasp by going to a jewelry store & having it replaced."
