Thank you BOTH for that information. My experience
with TK70 media did not have that happen often enough
that I realized there was a problem. But I will try to
remember to check the rollers next time.

I am holding in my hand a cylinder that is about 2 1/2" long
and about 2 3/4" in diameter. It probably weighs about
5 lb.. and if I remember correctly it was the voice coil
from an old speaker that was so badly damaged it no
longer worked. So a permanent magnet needs to be
fairly strong. I suggest that you might try to move your
magnet in a circular motion of about 4" in diameter while
toughing both large sides of the TK70 plastic container.
If you achieve partial success with a minute or two, then
maybe 5 minutes or even 20 minutes might be fully
successful although I would agree that 20 minutes for
every tape is too long. But it would at least prove that
the method works in principle.
