Abstract :
Effects of number of magnet in Halbach magnet system for producing homogeneous magnetic field It has been demonstrated that the field homogeneity of the Halbach magnet is high enough to be used in various versions of portable devices such as NMR relaxometer, and MRI. This study discussed effects of the number of magnets used in the Halbach magnet system, and compared their initial simulation outcomes. Two kinds of magnets settlements were modeled and investigated within a multidimensional framework. The simulation outcomes show that the settlements of permanent magnets play important role on the magnetic flux density and homogeneity at the center of the magnet design. The maximum magnetic flux density was obtained at the centre, as expected.
