Mechanical deformation in incompressible linear and nonlinear magnetic materials was
evaluated using various conventional electromagnetic volume and surface force density
methods. These conventional force density methods are the Maxwell stress tensor method,
Korteweg-Helmholtz force density method (KH), magnetic charge method, magnetizing
current method, and Kelvin force density method (KV). The total force values obtained using
these different force density methods were found to be the same and equal to the total force …
