Neodymium Magnets (The most powerful magnets on Earth)
Neodymium Magnets are the most powerful permanent magnets commercially available today. They can be over 15 times as powerful as a ceramic (refrigerator) magnets. This power must be respected or there will be consequences, especially with large magnets.
The magnets shown (grade N45 or higher) are very powerful, much more powerful than magnets most people have seen, and need to be handled with proper care. The magnetic fields from these magnets can affect each other from more than 12 inches away. Please note that these magnets are fragile. Even though they are coated with a tough protective nickel plating, do not allow them to snap together with their full force or they may chip, break, and possibly send small pieces of metal flying on impact. Larger magnets can easily bruise fingers and even break finger bones as they attempt to connect together. Always wear protective eyewear or safety goggles when handling the magnets. Keep magnets away from any magnetic based storage devices such as desktop or laptop computers, hard drives, floppy disks, cassette tapes, VHS tapes, or credit cards. A distance of at least 12" should be kept between magnets and these items at all times. Keep them away from computer monitors, VCR'S and TV's, non-electronic wrist watches etc. If you or someone in your household has a PACEMAKER or another electronic surgical implant, don't even think of ordering these items. Neodymium magnets are not suitable for children to play with, and should only be handled under strict adult supervision.
THESE ARE ABSOLUTELY NOT TOYS AND CAN BE VERY DANGEROUS! KEEP AWAY FROM CHILDREN!
THESE MAGNETS CAN EASILY CRUSH FINGERS!
WE WILL NOT BE HELD RESPONSIBLE FOR INJURY OR DAMAGE CAUSED BY THESE POWERFUL MAGNETS.
THESE MAGNETS ARE SOLD TO ADULTS ONLY AND REQUIRE AN ADULT SIGNATURE UPON DELIVERY.
If carrying one into another room, carefully plan the route you will be taking. Sensitive instruments like computers & monitors will be affected in an entire room. Loose metallic objects and other magnets may become airborne and fly at great speed to attach themselves to these magnets. If you get caught in between the two, you can be severely injured. These magnets will crush bones in the blink of an eye.
Two of these magnets close together can create an almost unbelievable magnetic field that can be incredibly dangerous.
Of all the unique items we offer for sale, we consider these items the most dangerous of all. Our normal packing & shipping personnel refuse to package these magnets - our engineers have to do it. This is no joke or exaggeration - and we cannot stress it strongly enough. You must be extremely careful - and know what you're doing with these magnets.
Two Supermagnets can very easily get out of control, crush fingers and instantly break ribs or even your arm if opposing poles fly at each other.
A small child recently lost his hand when his father left two #31 (shown in pic) supermagnets unattended. The child picked one up and when he approached the other magnet on a nearby table, it became airborne and obliterated his small hand.
Another man named Dirk lost his finger tip (shown in pic) due to carelessness involving Neodymium magnets. According to his own words:
That Sunday night I placed on of them a bit in line with one of the others but still within a safety distance (I thought) !!!
When I rotated the magnet the other raised it self upwards due to the same poles. I know that I thought (ooops ... take care) and before I knew it the one that raised itself upwards turned around and within a split second the two magnets collided to each other with the top-part of my finger between them. Due to the brutal force my finger was splashed and pushed out between the magnets leaving skin and my complete nail between the two magnets. The collision was so strong that on the carpet I found only some drops of blood spread around the magnets. Like you smash a hammer on a frikandel (is a Dutch snack, a sort of minced-meat hot dog).
He says that the magnets were 50 centimeters (20 inches) apart when they suddenly flew together.
How powerful are they?
Two 2" NIBs have a "Pull Force" of over 325 pounds when attached to a steel plate. The rule of thumb is that a NIB is attracted to another NIB with a force 1 1/2 times the attraction to steel. With these magnets the contact attraction is about 500 pounds of force.
A particular magnet may have a pull of 1,000 pounds on an 8" thick block of a certain Iron alloy... where on a piece of sheet metal, the same magnet may have a pull of only 10 pounds.
At 1/16" of an away from the magnet's face there could be thousands of pounds of pull, and at 12" away, a small BB will not even roll toward the magnet. Magnetic energy tapers off very quickly with distance, just like radiation and gravitational energy - it's known as the 'inverse square law'. Nd magnets in general will lift between 300 and 500 times their own weight - and even this figure can be misleading. Some Iron alloys have strong attractions to magnets and some do not attract at all.
The only way to determine if a magnet will work for your purposes is to physically test it in exactly the same conditions that it is intended to be used under. The thicker the magnet, the more pull it will have. As a 'ballpark' figure, a 1" cube can lift up to 125 pounds, and a powerful Supermagnet, such as Supermagnet # 42, can lift close to 1,000 pounds.
SO IN THE END I SAY...... DO NOT F**K WITH NEODYMIUM MAGNETS!!!!!!!!
