I have a P.K. ring (magnetic) and its quite useful. But I was wondering if there was a way of restoring/super charging these things. Possibly by wrapping it with a copper coil with an electric current? If anyone has tried this, thinks it might work, or knows a better approach let me know. I would hate to break it.

I'm almost positive you can't do anything to change the properties of the ring, or any other magnet for that matter. I could be wrong.

Mikey, so are so right.

A permanent magnet and an electromagnet are two completely different animals. Do you need to restore the magnetic field? A PK ring is a permanent magnet, and is designed to stay magnetized. If it has lost its power I'd be really surprised, but maybe somebody else that's had this experience can chime in.

If you just want to supercharge it, or make it stronger, this can't be done. You have to buy a stronger magnetic ring (i.e. N50).

Some magnets lose their power if they exposed to heat. Once that is done I don't think there is a way to restore it.

Always store magnets and rings ect, on metal this will keep them at fully charged.
and they will not loose their magnetism

I am not trying to restore it just trying to make it more powerful (sorry for the confusion). But apparently this cannot be done, I suppose I will have to invest in a new one if I want that power.

I was unaware of that Vinsmagic, thank you for the advice.

You'd need a fairly powerful electromagnet to match the power of the modern permanent magnets, thus lots of turns of copper with enough diameter to pass a rather large current. Magnetic fields add up, but they have to be aligned to each other properly. Align them the wrong way and you are just cancelling out field. That said, of course the magnets are going to try to align themselves. So it might be feasible(starts scribbling some arcane notes...)

Several things will cause 'permanent' magnets to lose their field: heat, shock and exposure to varying magnetic fields like AC power etc. I doubt anything in the home would have enough power to affect a rare earth magnet significantly.

I had the fortune of playing with some really powerful electromagnets in the lab at university. More than once did someone forget to remove their personal possessions before entering...credit cards, watches, mobile phones ZAP! Now that's magic!

Sorry to correct you, vinsmagic, but a neodymium iron boron magnet (which is what all PK rings are) will NOT loose its magnetic force if it doesn't have a keeper. That used to be the case with older magnets, but these new ones don't need it.

There are two ways to increase the magnetic force of a magnet: (1) add more magnets, and (b) direct the magnetic force. In the case of a PK ring, #1 is ruled out. However, if your ring is more than about 3 years old, I suggest you get a new one as more powerful magnets are available. As for #2, by directing the magnetic force, you can effectively making a magnet lift almost 1.5x as much (many parameters go into the effective increase). However, again, this is not practical in a PK ring.

RE: directing the field, Supermagnetman offers rings with the field directed across the diameter of the ring, as well as the usual "doughnut-shaped" field. There does seem to be some difference.

Curtis Kam has it right... supermagnetman.net has N50 rings and also diameter field rings.

The N50 ring is VERY STRONG... but... and a STRONG but... it looks HORRIBLE! It doesn't look like a ring. it looks more like you are wearing some odd machine part!

Cataquet thank you for the up date I havent been in school in over 50 years you are correct thinks have changed.

Why try to supercharge the ring -- maybe you can accomplish want you want by disguising a strong m****t in other ways -- for example, in a card case? Let your imagination go wild ;-)
