No.
Its takes a conscious effort and time multiple rapid passes of a ferrous object across a magnetic one direction to actually magnetize something and without continual efforts to keep it magnetized it will simply fade right away - add a bit of heat (like hot oil) and kaboom no more magnet.
Plus the way these work- if the filings did come loose they would simply flow into the filter pleats then either be held by the media or flow through because of size, but they wont come loose because the magnet is so strong.
In no situation I can see are you worse off with the magnet.
These are one of the only things that work without impeding flow, can be re-used, and cannot hurt but only help your engine.
Think of your filter and magnet as a tag team- working better together.
