[Analysis Case] Magnetization Analysis of a Cylindrical Magnet Considering Hysteresis "Hard Magnetism"
Using 'hyperbolic function approximation'! Determine the hysteresis loop with numerical values and hyperbolic functions.
Using the hysteresis analysis function, we conducted magnetization analysis of magnets with high coercivity. A cylindrical magnet was magnetized using a coil. The current was increased from 0[A] to a maximum value and then returned to 0[A]. The magnetic field in the space at that time was analyzed. The hysteresis analysis function uses "hyperbolic function approximation" as a method to represent the hysteresis loop in this case. The hyperbolic function approximation takes coercivity, remanent magnetization, and saturation magnetization as input values, and these values along with the hyperbolic function determine the hysteresis loop.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon's software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
