The main benefit is that losses in the windings are significantly reduced, allowing a reduction in the number of ampere turns used. This leads to a significant reduction in the amount of magnetic flux and hence fewer iron core lo ...

MAGNETISM
... Magnets exert forces on one another. They are similar to electric charges, for they can both attract and repel without touching, depending on which end is held near the other. Also, like electric charges, the strength of their interaction depends on the distance of separation of the two magnets. Whe ...
