A set of 2D steady state finite element numerical simulations of electromagnetic fields, eddy currents distribution and induction heating pattern has been done for different thicknesses of ametal workpiece. Comparison between the calculation results show the importance of workpiece thickness on induction heating process including electromagnetic field distribution, eddy currents pattern, heatin...

Physics Education research indicates that there is a significant gap between the learning obtained by students and what teachers expect. In the usual teaching the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time to solve problems in a more or less rote manner. However, Physics Education research has shown that the fundamental concepts of ...

This paper studies nanomachines (motion nanodevices) 11. ANALYSIS AND MODELING OF INDUCTION NANOMACHINES . . synthesized utilizing induction electromagnetics. In particular, the rotor currents are induced in the rotor short-circuited nanowindings due to time-varying stator magnetic Beld as well as motion of the rotor with respect to the stator. The electromagnetic torque results due to the inte...

This paper numerically investigates the application induction heating in weld-based additive manufacturing to reduce residual stresses. To avoid time-consuming transient electromagnetic calculation, the induction heat is assumed to be constant in the arc coordinate. Thermo-electromagnetic coupling analysis is performed only at a typical time to obtain the representative distribution of inductio...
