Hi
How does magnetizing force of a permanent magnet relate to magnetizing of steal rods of different sizes?
i.e. if I bring a permanent magnet and a piece of steal of the same sizes, put them together, the steal piece becomes magnetized.
what if I bring a much much larger piece of steal for the same size permanent magnet. how much magnetizing force will be in the tip of that big one?
is there a formula which takes size in account?
thx
