Electromagnetic monopole - sort of?

[Low-Q]

A much easier way to make a circular magnetic field, is to wind a toroid without iron core. I checked it out in FEMM using axisymmetric problem type. There is no field outside the toroid. Only inside the hollow part of the windings. The magnetic field goes one way in a circle. I will make one with a plastic core which have a small slot where I can enter the copper wire for easier winding.
Then test it out on the surface of a large doughnut magnet I have, and see what happens. If this work, I will make more coils, and see if it is possible to make a brushless motor that runs on pure DC.
