I would like you to think about the very powerful electromagnetic fields generated inside an MRI scanner and what effect they have on the blood, if any.
I would like someone to determine how much mass of actual iron would need to be immediately below the skin to hold a small magnet - and what color the skin would be? Because in my opinion, you'd need at least half a gram and the skin would be very red or brown. Maybe a little experimentation required with, say, a piece of paper and iron filings?

Don't forget moisture on the skin as well can help hold a magnet up so not much iron is needed in theory.
When you have new skin developing there is more blood flow and moisture at the injection site.
