Halbach Array Explanation


The Halbach array was created by Klaus Halbach for particle accelerator applications. The Halbach array is a special formation of magnets used to guide the magnetic fields to create a strong sinusoidal magnetic field below the array while nearly cancelling the magnetic fields above the array. A standard, simple method to create a Halbach array is to place magnets oriented 90 degrees to each other. Figure 1 illustrates a five magnet Halbach array with a wavelenght of four magnets. The sinusoidal magnetic field below the array is illustrated as well.
