Description
Halbach Array
 
   A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetisation.
 
  Halbach array can double the power of the magnets. This particular arrangement of the magnets, bound by means of glue allows to almost double the magnetic field from an array side while the other side the magnetic field is almost zero. The array of Halbach find practical applications in the maglev train and in particle accelerators.
