What is the proper term for a magnetic field/force through a ferrous/iron structure? I've beat my head against the wall trying to find the correct term in Google.
What I am after is how magnetic field from a permanent magnet is guided through a ferrous part in a machine. Such as in a small toy DC motor, the cheap style that has one magnet and two iron "fields" that the rotor turns in. Or like in a magnetic cabinet latch, the kind that has a magnet between two iron pieces, that hold a door closed.
Can anyone help with some suggestions on where to find more information?
