Think if you read my post eddy current losses occur in the core not in the windings. In a magnetic circuit there are eddy current losses and magnetisation losses. In the core as frequency rises laminated soft iron cores are replaced with ferrite cores and eventually air cores. When it comes to magnetisation losses they are depicted using a hysteresis curve. A permanent magnetic core will have a ‘fat’ hysteresis loop, while a good electromagnetic core has a ’thin’ hysteresis loop. Solid core conductors are also more prone to breakage.
