Neodymium Halbach Array Magnet

  • Descriptions:

Neodymium Halbach Array Magnet can produce higher flux densities in the air gaps of electromotive machines are described. It’s a very interesting arrangement of magnets. If you place them in a specific pattern you end up with most of the magnetic lines projected in one direction, and hardly any in the other.

This result in a magnet that sticks to a fridge one one side, but not on the other. Very weird! I put one inside a cylinder and it will always roll to one side on a metal object.

  • Applications:

Halbach magnet arrays have been widely used in permanent-magnet electrical machines since the mid 1980′s to enhance performance and efficiency. The Halbach array has the property of producing a relatively high magnetic field on one side of the array while cancelling the field on the other side of the array to near zero.
