Cool Gadgets - Super Magnets
Tagged Under : Unusual Gadgets

This is a technology blog, but we still reserve the right to review low tech gadgets and gizmos. Not sure why, but I always had a weakness for gadgets that I could put together and take apart. And now as an adult it seems like nothing has changed. I seem to have a more intensive fascination when the gadgets are dangerous or have dangerous applications. Well, the super magnets at United Nuclear seem to fit the bill.
The magnet page on the United Nuclear site advises the casual reader that the super magnets are dangerous and that fingers and bones could be crushed. When they are shipped to customers they must be shipped via ground service since the magnets could interfere with an aircraft’s navigational equipment. In fact, an adult signature is required in order to take delivery of the magnets to prevent children from accidents.
How about checking if your dollar bill is real ? Modern US bills use magnetic ink and you should be able to move a genuine dollar bill around with your magnet. The magnetic ink makes it more difficult to counterfeit US currency and allows vending machines, ATMs and bill counters to function properly.
For impressing young kids with magic tricks and science experiments, a super magnet steps up to the occasion. You can put the magnet in your pocket and showcase the power of magnetic fields or show them how the magnet can pick up a 60 lb weight.
When you have a garage that needs to be cleaned, its hard to beat a super magnet. The super magnet can help you collect nails, bolts, nuts, paper clips, tacks, wires and small tools that might be spread around in inconvenient locations where you can’t reach them easily.
If you have a reason to erase a lot of VHS tapes, credit cards, disk drives, etc. then you absolutely need a large neodymium super magnet. Of course, I dont know why anyone would need this functionality!
Magnet therapy is another reported application. Proponents say it helps cure carpal tunnel syndrome, lower back pain, etc. Its controversial whether these effects are true or if it is just the placebo effect. I am deeply skeptical, but who really knows?
Anyways, if you get a magnet have fun and let us know if you have any creative uses for your magnets.
