Poster: Design and electromagnetic finite element analysis of Novel Mandhala Halbach arrays for novelapplications.

Mandhala Halbach arrays are a flexible architecture to generate variable magnetic fields and

gradients that can be broadly applicable in fluid flow measurement, MRI image processing, and

many more portable applications [1, 2] . We will present a couple of new 2D and 3D concentric

Mandhala Hallbach arrays designs and electromagnetic and thermal properties finite element

analysis using Multiphysics software packages. We will also demonstrate the method of

optimization of the number of magnets required for the manufacturing without compromising the

magnetic field strength which will be a critical step of conserving the expensive sintered

magnets. We will also compare the feasible routes of manufacturing and associated technical

challenges such as frame integration and demagnetization.
