Amateur radio operators have played a longstanding game of “Will It Antenna?” If there’s something even marginally conductive and remotely resonant, a ham has probably tried to make an antenna out of ...

We develop a class of mixed finite element schemes for stationary magnetohydrodynamics (MHD) models, using the magnetic field 𝐵 and the current density 𝑗 as discretization variables. We show that ...

A new method allows welders with little background in magnetism to reduce arc blow during DC welding of pipelines. Arc blow most commonly occurs after an in-line magnetic-flux-leakage inspection tool ...

What Are FEM, FDM and FVM? FEM, FDM and FVM differ from one another in important ways. Understanding these distinctions is key to selecting the method most appropriate for your purposes. The ...
