## Batch heating of tube

 Application: General Software: ELTA 6.0/5.5 Type: Investigation Magnetic permeability is the most complicated physical property for simulation. In general, it is necessary to describe dependence of relative permeability upon temperature T and magnetic field strength H for each magnetic material. Accurate account for magnetic permeability is difficult due to three factors: magnetic hysteresis, non-linear dependence of Mu vs. field strength H and strong dependence of Mu from temperature when it approaches to Curie point.

ELTA 5.5 (6.0) was used to find a possibility to improve the heater.
