Numerical Study of Magnetoacoustic Signal Generation with Magnetic Induction Based on Inhomogeneous Conductivity Anisotropy
Numerical simulations on the cylindrical conductive models with isotropic conductivities. (a) Eddy current density, (b) Lorentz force density, (c) sound source density on the planes mm, , and , and (d) sound pressure on the plane mm at time , 30, 40, and 50 μs. The units of eddy current density, Lorentz force density, boundary source density, homogeneous source density, and sound pressure are, respectively, Ampere/m2 (A/m2), Newton/m3 (N/m3), Pascal/m (Pa/m), Pascal/m2 (Pa/m2), and Pascal (Pa).
