The Unbelievable Neodymium Magnet


The Unbelievable Neodymium Magnet

There have always been magnets made from everything from ceramics to the rubberized material used for refrigerator magnets and a thousand other items we’ve all used as many times, Alnico magnets by far being the strongest and most popular in industrial based products.

Twenty years or so ago, the whole world changed overnight with the introduction of the most incredible everyday device since krazy Glue, cold, chemical light sticks, hot glue guns, and lithium batteries…

Man made, rare earth, nickel-plated, neodymium magnets literally changed the world overnight. For one, there would be no hard drives in your computers if it weren’t for neodymium magnets. These little guys are perhaps hundreds of times more powerful than the old Alnico magnets depending on the size, shape and grade.

To give you an example, the quarter sized disk that’s less than a quarter inch thick shown in the photo could not be picked up if it was set down on a steel plate, You would have to slide it off to the edge of the plate with great difficulty or pry it up with a knife or chisel. Four, one inch by one half-inch neodymium block magnets would hold up a car engine with ease if suspended properly.

If you had two of those quarter size magnets shown in the photo stuck to each other, chances are, you wouldn’t be able to separate them unless again, you hammered a knife or something in between them. These things are nothing short of unbelievable and are responsible for thousands of modern day devices and inventions that just plain wouldn’t work without them.

Do you know how many different kinds of ways there have been to hold up hand tools on your work area wall? None of which from pegboards to just plain nails with the outline of the tool that belongs there ever worked very long. Now, for a little as .15 cents each, you can silicone a bunch of ¼ inch neodymium button mags up that will hold just about any hand tool you have. The workbench picture is in my son’s garage. You can’t get any simpler. The tools don’t have to be in any particular location and they simply stick up like magic.

A bit of caution, these are potentially dangerous magnets and should be handled with great care.

1…Keep them far away from all electronic devices as many devices work with magnetically sensitive components that can be destroyed or have their parameters changed in the influence of a strong, outboard magnetic field.This includes picture tubes or CRT’s from the older style television sets. I’m not sure but I don’t think I would want one near a heart pacemaker either.

2…The neodymium material is compressed into any shape imaginable then copper plated and finally given a coating of nickel. This material is very brittle so don’t even think of hitting one with a hammer. If the plating breaks, which it will, you’ll have a hundred little super sharp chunks of neodymium on everything metal that magnets stick too. In fact, if you happen to be standing next to a thick steel frame from anything at all and you break a powerful neodymium magnet while your in between the two, you're likely to be skewered by the very sharp magnet chips racing toward the steel plate.

3…I have been pinched many time by two of these little monsters slamming together, the power in incredible.

4…Do not ever try to drill holes through these magnets. The process will produce a toxic gas and you will also destroy the magnet. Use silicone if you need to glue them down to something. Hot glue or Krazy glue won’t last for long.

Neodymium’s can be bought in dozens of places online and even a one inch, super powerful magnet will only cost you 10 or 15 dollars but unless you have a need for the big boys, don’t buy any, you’ll probably hurt yourself with it. The little button mags shown in the picture are cheap and can be use for tons of application around the house. Keep them away from pets and kids just like you would any other dangerous tool.

Interesting hub. I have seen stories about these magnets on TV but have never owned or held one. I have heard they can be dangerous if stored or used improperly. Thanks for the information. I do a lot of metal detecting and I was thinking about getting one of these magnets attached to my digging tool. The problem is I'm a little nervous about having one of these powerhouses around my expensive detector. I wouldn't want to harm the electronics by accident. I guess I'll have to give this more thought. Thanks again for the heads up. Voted this hub up!

Small world Point2Make...

I've been treasure hunting with metal detectors for 45 years now. As a matter of fact, I just published a book called "Treasure In Your Backyard" that is featured here on Hubpages...http://hubpages.com/games-hobbies/TREASURE-IN-YOUR...

I don't know why you would want to use a magnet while treasure hunting with a metal detector. All the good stuff won't stick to any magnets. If I would have kept all the junk iron and steel I've passed over during the years, I'd have enough to build a couple freight trains. Earth is loaded with natural iron and man made steel. With gold at $1,800.00 dollars an ounce these days, Iron and steel are the last things I want to find.

I'm an electronics tech and I doubt a magnet if kept by the search coil on your detector would affect a problem. The search heads just contail coils of copper wire. I wouldn't mess around with the main unit however. Who knows? Send me your address and I'll send you a couple little button mags you can play around with. I got a ton of them.You won't believe how powerful they are..

Good luck with your digs...

Hi Craig, The book looks like a great deal....I'll add it to my collection shortly.

I was thinking about using the magnet with my digging tools, as I also hunt for meteorites and a magnet is a great tool for helping to identify meteorites. I have found a couple ,so far, and a good magnet will make the hunt a lot easier.

Tomorrow I leave for a 3 day beach hunt on the south coast of Nova Scotia. The detectors are all ready to go and hopefully the weekend will be profitable...but if not the area and the setting will be worth the effort. I love beach hunting and these beaches are virgin territory for detecting.

There was a guy a couple years ago someplace on the mainland of England that discovered a cash of mostly gold and silver military weapon adornments and other loot taken from defeated army's a couple hundred years ago. It was buried way out in the middle of a huge field and worth an untold fortune. I recently sold a 12 hundred dollar Whites top of the line detector to an English guy that looked for undiscovered World War Two aircraft that went down that still contained MIA's. That was a good detector except on a beach with wet sand, forget it. It went crazy. I'm told all Whites units do that due to the type of transmisson they use as opposed to Garret which uses a pulsed transmitter that stays reliable by the waters edge.

This sounds like a fun hobby to treasure hunt! I would be afraid to be around dangerous magnets so probably will never treasure hunt.

Hiya Marie...Missed ya..

Nah! Point2Make also hunts for meteorites. That's why he uses a magnet I guess. There's no magnets used in general treasure hunting with metal detectors.You ought to try it. It's a great hobby and could possibly make you rich.

AEvens said you had a positive break through with your hearing. True? If it is, I want to be the first one on your Skype list ya hea.

Lots of stuff going on since we spoke last. AEvans and I are co-authoring the scifi book I was working on and I'm helping her get her Friends of Furry Friends dream become a successful reality. She's as sharp as a tack so with my good looks and her talent, we ought to be able to get a lot done. LOL Check out the Fundly site she optionally gives to anyone that wants to help:

www.fundly.com/craigsuits.You can drop a couple bucks there while your at it. I won't mind. Currently 100% of all donations go to destitute animals.

Anyway, really great hearing from you again. You were like my right hand with that Tatjana thing. Ok ok...the left one too. I just dropped her a note a few days ago to see how she was doing.

Don't want to loose her again for Christ sake.

Seeya round the campus Kiddo. Be good!

Hiya Craig, Yes, I have been doing self-healing and early this week I was in my office with the door closed and was listening to my s/o making noise outside. I didn't realize I was hearing until he came into my office. I got all the hearing I lost last month and with a little extra decibels (I take hearing tests). I am still hearing impaired but not deaf. The next step is to heal completely. I am very grateful!

Great to hear you are working with Julianna with the book! Will check out the animal site too. I have sold about 15 copies of my book, not sure yet if it's more as I don't get the full reports until I believe the end of the month.

Great to hear about your hearing, At least that shows it's not nessasarily permanent.

I believe you sold at least 16 copies of your book. I don't get into that mushey stuff myself but my daughter inlaw does. I just spend 4 hours babysitting last week while she was at the mall getting a book signed. Send me the address. I don't even know what the name is.

Seeya...
