If I dropped into a black hole a magnet. Why could I follow the path of
the magnet, once it passed the event horizon?
Consider the tidal forces outside the event horizon. You need
first to understand all that's happening outside.
The tidal forces can be as small as one wishes to connsider by
assuming a large enough black hole mass. In principle, the gravitational
field at the horizon could be 1 g (or less).
