TL;DR: This is extremely dull and predictable (an amulet shaped like Mjolnir that shocks people that come too close), is too short to make any real impact and basically lacks a hook. Your reader will find themselves going: "So?" after reading the article. There really isn't anything salvageable in the concept or the execution. I'd advise you to read recently posted successful articles, How to Write an SCP, the Guide for Newbies and to participate in and read the forums for a while to get a better handle on what we're looking for. Otherwise you'll just end up seeing your article, which I assume you're spending solid time and effort on, go down in flames and end up deleted.
Yeah you Know What, Fuck it Im Not even Gonna Bother Anymore.
That's certainly a route you could take, or you could really put some effort in and try to catch on to what makes a successful article.
