magnetic lines of force

[mag′ned·ik ′līnz əv ′fȯrs]
(electromagnetism)
Lines used to represent the magnetic induction in a magnetic field, selected so that they are parallel to the magnetic induction at each point, and so that the number of lines per unit area of a surface perpendicular to the induction is equal to the induction. Also known as magnetic flux; magnetic lines of flux.

In other words, the resistance offered by the porosity of the medium is much more than the resistance due to the magnetic lines of force.
The magnetic lines of force created extend into the casting, which in turn induces the flow of eddy currents.
It also appears to have a remarkably well ordered structure that resembles the bar magnet pattern--exemplified by magnetic lines of force looping from the north pole to the south pole--exhibited by Earth and the sun.
