I know that some stainless steels are attracted to magnets, but has anyone seen it act like it's a weak magnet? I was using my pocket knife, an older Gerber 450 E-Z-OUT made of "400 series stainless steel"---whatever that means, to point to something on my monitor and noticed that the color changed and bent slightly around the knife blade. I figured it had a magnetic field and didn't use it any more on the screen.
I replaced my crappy old monitor with a another one (older Gateway EV700 $5 at a thrift store ). I decided to test steels against the crappy old monitor. I used various guns and knives, carbon and stainless. The only other peice of metal that affected the montor was one of my brother's cheesy Chinese throw away knife that was stainless. Of all the metals tested only the two stainless steel blades did this.
Is there any advantage or benefits to testing the magnetic field of stainless steel, such as being able to tell the difference between classes of steels? Could being magnetic be a sign of a lesser quality stainless steel?
