3 INCH ROUND MAGNET

[nomad 11]

i went to harbor freight saturday to see what they had for magnets. they had a 3 inch round neodymium magnet for $2.99 with coupon and membership card. 95 lb pull. i never heard of this membership before ? i'm thinking this will be a good magnet to start out with. then i find out that the membership is 45 smackers a year. wheres the savings ? i only need things here and there. so i walked out without my magnet and the search continues ? why does'nt walmart have chinese magnets ? they have basically everything else ?

Hi N-11, I purchased a NDM 500 lb lift $60 Canadian I lost that one it grabbed something "flat on!!" and eventually the rope broke so not to be deterred I bought another and this time I applied a rope with more lifting power than the Magnet. Only just got into this hobby so am feeling very ambitious for spring.....HH....Bonz

For those high cap magnets, you need a tall rope loop to insure that when that happens and you pull from the side the magnet will tip off what ever it is stuck to. I got mine stuck on a bit of metal frame on a dock and my long handled shovel was all that saved it for me. Pulling from different directions if possible is also very helpful.

Hi BW, at the time side pulls were tried, it was in 8 feet of water and must have stuck to a piece of the steel bridge that was there, the rope was only at 300lb strength so the math didn't equate and that was that, now have a 600lb rope and waiting for spring.....HH....Bonz

Yeah - I'm sure Walmart will get in the business soon enough. One thing to be careful about is the pull force of magnet vs. it's surface area. 95lb pull force on a 3 inch round is not very much. If you only really care about small stuff, nuts, bolts fishing tackle etc then this type of magnet is totally fine. As you get more surface area though the magnet needs a much larger surface to stick to in order to fully utilize the 95lb pull force. For a 3 inch magnet I would assume at least 300lb of pull force would be ideal. The wider the magnet the more angle that is created when you pull up. You pull in one direction, if the magnet has a large surface area it cocks to the side and will tend to slide off the item, these magnets work best if pulled perpendicular to the strength of the magnetic field otherwise you depend too much on friction. It's easier to slide a magnet on your refrigerator than pull it straight off. Plus the 3 incher just doesn't fit in your pocket well.
