A nice sized small nickel plated neodymium magnet with this description from Wondermagnet.com We are proud to offer a super powerful nickel plated Neodymium Iron Boron block magnet of very impressive size and strength. One of these magnets will lift over 100 pounds of iron! These are abnormally strong magnets, and serious care must be taken in storing and handling these. Being block magnets, these have sharp corners like TEETH, and being large, they have vicious attraction to one another like JAWS. When they come together, they do not let go easily. Make a mistake with these and you will probably bleed. Like all sintered Neodymium magnets, these are somewhat brittle. Not for children...obviously-and not for toys. If you have not handled Neodymium magnets before, please order something smaller so you understand the dangers here. One of these will noticably distort a computer monitor from over 30" away. Keep these well away from electronics, and magnetic storage medium. Don't buy these if you have a pacemaker. We take no responsibility for injury, or property damage resulting from the mis-handling of this, or any other magnet we have to offer. Item #5 $15.00 then This is a complete magnetic assembly surplus from the computer hard drive industry. Each assembly is held together with 4 screws. You'll need a #9 Torx bit (a #8 works as well), or an allen wrench to disassemble these. Once disassembled you'll find 2 Neodymium magnets inside. They are just short of 2" long, about 1/16" thick and 3/4" tall. Each magnet is glued down to its steel bracket. These are an excellent value, the magnets are of very high grade and will easily lift over 30 pounds of iron. Remember, some dis-assembly required!
