There are two mechanisms of energy absorption:

- generation of close-loop (eddy) currents inside the body which cause heating due to electrical resistance of the body material

- hysteresis heating (for magnetic materials ONLY!) due to a friction of magnetic micro volumes (domains), which rotate following orientation of external magnetic field

Part 1 deals mainly with electromagnetic phenomena in induction heating systems.</p>", "tags": [], "price": "0.00", "invite_message": null, "allow_score_reset": true, "igtype": "ignitable", "pass_email_text": null, "fail_popup_text": null, "podcast": false, "public_views": 8305, "notification_email_text": null, "categories": [], "overdue_days_email_text": null, "pass_action": "", "notification_days_before": null, "access_token": null, "pass_popup_text": null, "pass_level": 0, "author": 438, "completion_date": null, "overdue_summary": false, "fail_retake_auto": false, "avgrating": "0.0", "directory": "OU49zjJ8wF", "date_created": "2009-03-26T10:56:33Z", "access_token_limit": 0}, "model": "Content.ignitable", "pk": 1054}]
