They are caused by the changing magnetic field in the armature. Eddy currents can cause heating and loss of power in the armature. The laminations are made of thin sheets of steel that are insulated from each other. This prevents the eddy currents from flowing from one sheet to another. The laminations are also stacked with a small air gap between them. This further reduces the eddy currents.<\/p>\n<p>The <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\"
