Magnetic Particles in Nurofen Tablets

This is worth looking into but I do have a couple of questions.

What are these particles? The lady in the video says that they are graphene oxide but I don't know why she's so certain.

What is the source of the water she's using? Might the particles be coming from the water itself as it reacts with something in the tablets?

Whatever the answers, this still looks like something to be concerned about.
