1 Neodymium Magnet 6 x 2 inch Disc N48 HUGE STRONG
Can hold up to ***1175 POUNDS *** Well over 1/2 Ton!!

Remove all metal objects within a 5 foot radius before unpacking. Magnets of this size and strength can pull metal objects to them when brought too close.

lol how is it even possible to ship that. It would get stuck to the side of the van.

field dies off rapidly with distance. Crate it in a 2ft box. You can also "shield" a majority of the field.

IIRC, the force from a dipole magnet drops off as an inverse-cube relation when the distance from the magnet is "large" compared to the distance between the dipoles. So basically put it won't magically jump up and connect onto the wall of a truck from a foot away, most likely the package it as such in fact.

I figured as much, Still would be funny though.

Actually.....could you do that with a nano?

I'll bet that would do a number on your hard drive!

I wonder what they would actually use this for? A huge refrigerator?

It looks painful to me.
