We have derived the corresponding finite element formulation which takes the mechanical displacement, the magnetic potential, and the magnetization vector as the field variables, according to variational principle.
The magnetic field distribution model of the permanent magnet array is established by using the scalar magnetic potential model.
The magnetic potential energy of the nuclei is calculated according to equation (7) as −mB.
Today, Coulomb's law refers only to charges, but historically it provided the foundation for a magnetic potential analogous to the electric potential.
(3.12) Notice that the magnetic potential (varphi_{0}) satisfies (3.2).
Herein we have neglected magnetic potential and thermoelectric effects.
The Earth's gravitational or magnetic potential can be approximated by a truncated series of spherical harmonics.
For the superquadratic case with magnetic potential, we refer the reader to [35] and references therein.
The method of the reduced scalar magnetic potential is applied to optimise the computational cost.
In the numerical simulation, the Maxwell equations are solved to obtain the magnetic potential.
The magnetic potential energy is given and the electromechanical equations are derived.
