His principle states that magnetic lines of force are carried along in a moving fluid like strands of thread cast into a river, and thus they can never "break" and reconnect.
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.
