I am analyzing the effects of magnetic and electric fields generated when current flows through an insulated coil using the Eddy Current mode, and I have some questions about its analysis method.&nbsp;&nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;1. From what I understand, the current used in this mode is typically sinusoidal. Thus, when a sinusoidal current flows, the generated magnetic field changes over time, inducing an electric field in the opposite direction according to Maxwell&#8217;s equations. Consequently, when a sinusoidal current flows, an induced electric field with a phase of -cosine should be generated. However, in the Eddy Current mode, it seems that the phase of the induced electric field aligns with the phase of the current, both having a sinusoidal phase. I am curious why this result occurs. (I used 1kHz)&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;2. I have also observed that this phenomenon varies depending on the analysis frequency. Why does the result change with frequency, and how can we predict these changes?&nbsp;&nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;3. Additionally, I would like to understand how enabling or disabling the Eddy Effect within the Eddy Current mode affects the analysis.&nbsp;&nbsp;&lt;br&gt;&lt;br&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/15-11-2024-1731661485-mceclip2.png\" width=\"383\" height=\"337\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/15-11-2024-1731661509-mceclip3.png\" width=\"370\" height=\"332\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/15-11-2024-1731661462-mceclip1.png\" width=\"404\" height=\"332\" \/><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/11\/15-11-2024-1731661536-mceclip4.png\" width=\"387\" height=\"323\" \/>&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;I look forward to your smart and insightful answers to help resolve these issues. &nbsp;&lt;\/div&gt;&lt;div&gt;&nbsp;&lt;\/div&gt;&lt;div&gt;Thank you.&lt;\/div&gt;<\/p>\n","protected":false},"template":"","class_list":["post-394005","topic","type-topic","status-publish","hentry","topic-tag-ansys-electronics-desktop","topic-tag-eddy-current-1","topic-tag-eddy-current-solver"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello, I am using Ansys software to study microcoils.
