5) What is a Halbach array and how is it used in electric motors?

A Halbach array is arrangement of permanent magnets that creates a stronger field on one side while reducing the field on the other side to near zero. This is accomplished by orienting the magnets so that their poles are out of phase, typically by 90 degrees. This orientation essentially re-routes the magnetic field below the structure (the “non-working” surface) to the plane above the structure (the “working” surface), strengthening the magnetic field of the working surface and reducing the field of the non-working surface to nearly zero.
