Description: Permanent magnet machines for electric vehicles are
often designed with a magnetic saliency to improve the torque
generation as a result of the reluctance torque at field-weakening
operation. The armature reaction is pronounced in such
operation, leading to extensive magnetic field harmonics in the
teeth and consequently iron losses. This paper analyses the iron
losses in two designed machine topologies, inset and interior
permanent magnet rotor structures, by measurements and finite
element method computations. The measurements and
calculations are performed on three prototypes - one with an inset
design and two with an equal interior design, but different
laminated stator core sheet thickness of 0,35 and 0,20 mm,
respectively. The three machines have the same stator designs and
water-cooled housings.-Permanent magnet machines for electric vehicles are

This MATLAB M-file implements the finite-difference time-domain
solution of Maxwell s curl equations over a three-dimensional
Cartesian space lattice comprised of uniform cubic grid cells.
Each unit cell within the Yee lattice contains electric field
components sampled along the edges of the cube and magnetic field
components normal to the faces of the cube (the dual of Fig. 3.1).

Description: The function implements an horizontal magnetic dipole (along the x-axis) and calculates the x and z component of the magnetic field for y=0. The script allows to set a wanted value of multiple layers, with their own relative electric permittivity, relative magnetic permeability, conductivity (see the LAYERS PARAMETERS section in the script). The script finally produces an animation of the radiated field.

Description:
A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength) as such it is a vector field. Magnetic fields can be produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.-
