The input voltage is adjusted to use a voltage that results in a maximum value of the current density (absolute value) of 1!
This is a case study that confirms the current distribution observed when an alternating current is passed through a conductor bundled with 19 strands of wire, using magnetic field analysis. Since frequency response magnetic field analysis is appropriate, the software "PHOTO-EDDYjω" was selected. The input voltage was adjusted to ensure that the maximum value of the resulting current density (absolute value) is 1. As a result, at a frequency of 1×10^5 [Hz], the current density was almost constant, while at a frequency of 1×10^7 [Hz], a concentration of current density was observed on the surface of the outermost layer of the conductor. 【Case Summary】 ■ Software Used: PHOTO-EDDYjω ■ Analysis Results ・1×10^5 [Hz]: Almost constant ・1×10^6 [Hz]: Gradual distribution of current density observed ・1×10^7 [Hz]: Concentration of current density observed on the surface of the outermost layer of the conductor *For more details, please refer to the related links or feel free to contact us.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. 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 reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
