Default Re: Metal Particles on Spark Plug ?

There shouldn't be any metal particles on your spark plug. Metal particles are a sign of something is wearing in the engine.
And a magnet will will only attract ferrous metals. Your particles are aluminum.
You could have a broken ring that's "machining" a groove in the cylinder wall each time you start the engine.

If it was my engine, I'd tear it down to see what's causing the metal particles.
