Steady electric and magnetic fields
WebA 2D model of laser melting consisting of heat transfer, hydrodynamic flow, surface tension, and a free surface motion was established. A physical field simulation of the laser melting process was performed, and the effect of steady magnetic field parameters on the internal flow and temperature fields of the melt pool was analyzed and validated by experiments. … WebWhich states that the Static electric field vector is an irrotational vector. Static field implies the time-varying magnetic field is zero, ⇒ − δ B → δ t = 0 ⇒ × E → = 0 Hence it is an irrotational vector. Maxwell’s Fourth Equation It …
