demagnetise वाक्य

:A AC current can also demagnetise metal without the risk of dents, but unless you have a safe AC source, such as an adjustable voltage pack, I wouldn't recommend it . "'s "'murrayinch Talk ) 14 : 00, 4 July 2006 ( UTC)
i know you can demagnetise a magnet with an impact but if i need to put a magnet in something that will recive impacts ( average 10 to 20 pounds ), if i try to dampen the impact with a layer of rubber or something better would it be easy or at least possible to lower it enough to not any magnetic strenght?
