text: The process I am about to tell is highly dangerous. So it is better advised to wear rubber gloves before starting. Steel unlike soft iron has the property by which it can retain some magnetic properties after passing electricity for some time. So take the stainless steel object and get two wires and connect one of the end of both the wires to the each of the two sockets in the plug and connect the other ends each to the steel object and leave it for some time. After some time disconnect the wires and you will get a magnet.
